+# Changelog
+
+All notable changes to the Rustelo project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Fixed
+- **rustelo_server**: Resolved 302 compilation errors after dependency updates
+  - Removed duplicate module declarations (`auth`, `content`) in lib.rs
+  - Fixed incorrect imports: `rand_rustelo_core_lib` → `rand_core`
+  - Fixed incorrect imports: `rustelo_client` → `client` in email providers
+  - Removed non-existent `rustelo_utils` import from version_control module
+  - Corrected RBAC module paths: `rbac_config` → `config`, `rbac_service` → `service`
+  - Added missing tower-http features: `cors` and `trace` in Cargo.toml
+  - Implemented `Display` trait for `ResourceType` enum in rustelo_core_lib
+  - Fixed clippy warnings: unused variables, redundant closures, needless borrows
+  - Fixed trailing whitespace in all source files
+
+### Changed
+- Temporarily disabled RBAC module (requires refactoring)
+- All workspace crates now compile with zero clippy warnings in strict mode (`-D warnings`)
+- Code formatted with `cargo +nightly fmt`
+
+## [0.1.0] - Initial Release
+
+### Added
+- Initial Rustelo framework architecture
+- Modular workspace with 17 crates
+- Foundation layer (core-lib, components, pages, client, server)
+- Framework layer (core, auth, content, web, cli)
+- Feature-based architecture with cargo features
+- Language-agnostic routing system
+- Configuration-driven content management
+- Authentication support (JWT, OAuth2, 2FA, RBAC)
+- Database abstraction (PostgreSQL, SQLite)
+- Email system with multiple providers
+- Cryptography utilities (AES-GCM)
+- Content processing (Markdown, templating)
+- Development tooling and CLI

+# Rustelo Foundation Integration Guide
+
+## Overview
+
+The Rustelo Foundation provides a complete ecosystem of library crates for building modern web applications. This guide shows how all foundation crates work together to create powerful, maintainable applications.
+
+## Foundation Architecture
+
+```
+Application Layer (Your Implementation)
+├── main.rs (imports and uses foundation libraries)
+├── build.rs (uses foundation build utilities)
+└── Cargo.toml (depends on foundation crates)
+
+Foundation Library Layer
+├── server/          # Server-side library with importable main functions
+├── client/          # Client-side library with app mounting functions  
+├── components/      # Reusable UI component library
+├── pages/           # Page generation and template system
+├── core-lib/        # Shared utilities and business logic
+└── core-types/      # Shared type definitions
+```
+
+## Complete Application Example
+
+### 1. Application Structure
+```
+my-rustelo-app/
+├── Cargo.toml           # Workspace and dependencies
+├── build.rs             # Build-time page generation
+├── src/
+│   ├── main.rs          # Application entry point
+│   └── lib.rs           # Application library code
+├── content/             # Markdown content and configuration
+├── templates/           # Page templates
+└── public/             # Static assets
+```
+
+### 2. Cargo.toml - Foundation Dependencies
+```toml

+
+### 3. build.rs - Foundation Build Integration
+```rust
+//! Build script using foundation build utilities
+

+
+## Cross-Crate Communication Patterns
+
+### 1. Configuration Flow
+```rust
+// core-lib loads and validates configuration
+let app_config = core_lib::config::load_app_config("config/app.toml")?;
+
+// server uses configuration for setup
+let server_config = server::ServerConfig::from_app_config(&app_config);
+
+// components use configuration for theming
+let theme_config = components::theme::ThemeConfig::from_app_config(&app_config);
+
+// pages use configuration for content processing
+let page_config = pages::PageConfig::from_app_config(&app_config);
+```
+
+### 2. Content Processing Pipeline
+```rust
+// core-lib processes raw content
+let processor = core_lib::content::MarkdownProcessor::new(&app_config.content_path);
+let content_items = processor.process_all().await?;
+
+// pages generates pages from processed content
+let page_generator = pages::PageGenerator::new()
+    .with_content_items(content_items)
+    .with_templates_from_config(&app_config);
+
+// components display the content
+let content_display = components::content::ContentManager::new()
+    .with_content_source(content_items)
+    .with_layout("grid");
+```
+
+### 3. Type Safety Across Crates
+```rust
+// core-types defines shared types
+use core_types::{ContentItem, User, Route, AppError};
+
+// All crates use the same types for consistency
+fn process_content(item: ContentItem) -> Result<ContentItem, AppError> {
+    // Processing logic
+}
+
+fn render_user_profile(user: User) -> impl IntoView {
+    // Rendering logic
+}
+
+fn handle_route(route: Route) -> Result<(), AppError> {
+    // Routing logic
+}
+```
+

+
+### 1. Multi-Stage Build Process
+```rust
+// build.rs orchestrates all foundation build utilities
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Stage 1: Core configuration processing
+    core_lib::build::process_configuration()?;
+    
+    // Stage 2: Content processing and validation
+    core_lib::build::process_content()?;
+    
+    // Stage 3: Page generation
+    pages::build::generate_pages()?;
+    
+    // Stage 4: Route generation
+    server::build::generate_routes()?;
+    
+    // Stage 5: Asset processing
+    process_static_assets()?;
+    
+    Ok(())
+}
+```
+
+### 2. Feature Flag Coordination
+```toml
+# Features are coordinated across all foundation crates
+[features]
+default = []
+
+# Core features
+auth = ["server/auth", "core-lib/auth", "core-types/auth"]
+i18n = ["server/i18n", "client/i18n", "pages/i18n", "core-lib/i18n"]
+content-db = ["server/content-db", "pages/content-db", "core-lib/content-db"]
+
+# Rendering features  
+ssr = ["server/ssr", "pages/ssr", "components/ssr"]
+hydrate = ["client/hydrate", "pages/hydrate", "components/hydrate"]
+
+# Development features
+dev-tools = ["server/dev-tools", "client/dev-tools"]
+```
+
+## Advanced Integration Patterns
+
+### 1. Plugin Architecture
+```rust
+// Define plugin traits in core-types
+pub trait ContentProcessor {
+    fn process(&self, content: &str) -> Result<String, ProcessingError>;
+}
+
+// Implement plugins in various crates
+impl ContentProcessor for pages::MarkdownProcessor {
+    fn process(&self, content: &str) -> Result<String, ProcessingError> {
+        self.process_markdown(content)
+    }
+}
+
+// Register and use plugins through core-lib
+let processor_registry = core_lib::plugins::ProcessorRegistry::new()
+    .register("markdown", Box::new(pages::MarkdownProcessor::new()))
+    .register("handlebars", Box::new(templates::HandlebarsProcessor::new()));
+```
+
+### 2. Event System
+```rust
+// Define events in core-types
+#[derive(Debug, Clone)]
+pub enum AppEvent {
+    ContentUpdated(ContentItem),
+    UserAuthenticated(User),
+    RouteChanged(Route),
+    ThemeChanged(String),
+}
+
+// Emit events from various crates
+// In pages crate
+self.event_bus.emit(AppEvent::ContentUpdated(content_item));
+
+// In server crate
+self.event_bus.emit(AppEvent::UserAuthenticated(user));
+
+// Listen to events in components
+self.event_bus.subscribe(|event| match event {
+    AppEvent::ThemeChanged(theme) => update_theme(theme),
+    AppEvent::ContentUpdated(item) => refresh_content_display(item),
+    _ => {}
+});
+```
+
+### 3. State Management Integration
+```rust
+// Global state defined in core-types
+#[derive(Debug, Clone)]
+pub struct AppState {
+    pub user: Option<User>,
+    pub theme: Theme,
+    pub language: Language,
+    pub content_cache: HashMap<String, ContentItem>,
+}
+
+// State management in core-lib
+pub struct StateManager {
+    state: RwSignal<AppState>,
+    event_bus: EventBus,
+}
+
+impl StateManager {
+    pub fn update_user(&self, user: Option<User>) {
+        self.state.update(|state| state.user = user);
+        if let Some(user) = user {
+            self.event_bus.emit(AppEvent::UserAuthenticated(user));
+        }
+    }
+}
+
+// Use state in components
+#[component]
+pub fn UserProfile() -> impl IntoView {
+    let state = use_context::<StateManager>().unwrap();
+    let user = create_memo(move |_| state.get_user());
+    
+    view! {
+        <Show when=move || user.get().is_some()>
+            // Render user profile
+        </Show>
+    }
+}
+```
+
+## Testing Integration
+
+### 1. Cross-Crate Testing
+```rust
+// Integration tests that span multiple crates
+#[cfg(test)]
+mod integration_tests {
+    use super::*;
+    
+    #[tokio::test]
+    async fn test_full_content_pipeline() {
+        // Use core-lib to load configuration
+        let config = core_lib::config::load_test_config().await.unwrap();
+        
+        // Use pages to process content
+        let content = pages::process_test_content(&config).await.unwrap();
+        
+        // Use components to render content
+        let rendered = components::render_test_content(content).await.unwrap();
+        
+        // Verify the full pipeline
+        assert!(rendered.contains("expected content"));
+    }
+    
+    #[test]
+    fn test_type_consistency() {
+        // Verify types work across crate boundaries
+        let content_item = core_types::ContentItem::new("test", "Test Content");
+        let processed = core_lib::content::process_item(content_item.clone()).unwrap();
+        let rendered = components::content::render_item(&processed);
+        
+        assert_eq!(processed.id, content_item.id);
+    }
+}
+```
+
+### 2. End-to-End Testing
+```rust
+// E2E tests using all foundation crates together
+#[cfg(test)]
+mod e2e_tests {
+    use super::*;
+    
+    #[tokio::test]
+    async fn test_complete_application() {
+        // Start server using server foundation
+        let server_handle = server::test_utils::start_test_server().await;
+        
+        // Generate test content using pages foundation
+        pages::test_utils::generate_test_pages().await.unwrap();
+        
+        // Test client-side functionality
+        let client_test = client::test_utils::TestClient::new()
+            .navigate_to("/")
+            .expect_content("Welcome")
+            .navigate_to("/blog")
+            .expect_content("Blog Posts")
+            .run()
+            .await;
+            
+        assert!(client_test.passed());
+        
+        // Cleanup
+        server_handle.stop().await;
+    }
+}
+```
+
+## Deployment Integration
+
+### 1. Production Build
+```bash
+#!/bin/bash
+# Build script using all foundation capabilities
+
+# Build server with all features
+cargo build --release --features "ssr,auth,content-db,i18n,metrics"
+
+# Build client for WebAssembly
+wasm-pack build --target web --features "hydrate,router,i18n"
+
+# Generate static pages
+cargo run --bin page-generator --features "generation"
+
+# Process and optimize assets
+cargo run --bin asset-processor
+
+# Create deployment package
+tar -czf rustelo-app.tar.gz target/release/server pkg/ generated/ public/
+```
+
+### 2. Docker Integration
+```dockerfile
+# Multi-stage Docker build using foundation crates
+FROM rust:1.70 as builder
+
+# Copy foundation source
+COPY rustelo/crates/foundation /app/foundation
+COPY . /app/src
+

+COPY nginx.conf /etc/nginx/nginx.conf
+
+# Start script that runs both server and nginx
+COPY start.sh /start.sh
+RUN chmod +x /start.sh
+
+CMD ["/start.sh"]
+```
+

+# Rustelo Foundation Library System
+
+A complete, modular foundation for building modern web applications with Rust, Leptos, and WebAssembly.
+
+## 🎯 Overview
+
+The Rustelo Foundation provides a comprehensive set of library crates that work together to create powerful web applications. Each crate is designed as a reusable library with importable functions, extensive documentation, and practical examples.
+
+## 📦 Foundation Crates
+
+### Core System
+- **[`server/`](crates/server/)** - Server-side library with importable main functions, routing, and middleware
+- **[`client/`](crates/client/)** - Client-side library with app mounting, hydration, and state management  
+- **[`core-lib/`](crates/core-lib/)** - Shared utilities, configuration, i18n, and business logic
+- **[`core-types/`](crates/core-types/)** - Common type definitions and data structures
+
+### UI System
+- **[`components/`](crates/components/)** - Reusable UI component library with theming support
+- **[`pages/`](crates/pages/)** - Page generation system with templates and content processing
+
+## 🚀 Quick Start
+
+### 1. Import Foundation Libraries
+```rust
+// In your application's Cargo.toml
+[dependencies]
+server = { path = "path/to/rustelo/crates/foundation/crates/server" }
+client = { path = "path/to/rustelo/crates/foundation/crates/client" }
+components = { path = "path/to/rustelo/crates/foundation/crates/components" }
+pages = { path = "path/to/rustelo/crates/foundation/crates/pages" }
+core-lib = { path = "path/to/rustelo/crates/foundation/crates/core-lib" }
+core-types = { path = "path/to/rustelo/crates/foundation/crates/core-types" }
+```
+
+### 2. Use Foundation Main Functions
+```rust
+// src/main.rs - Import and use server main function
+use server::{run_server, ServerConfig};
+
+#[tokio::main]
+async fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Simple usage - use foundation server directly
+    run_server().await?;
+    Ok(())
+}
+```
+
+### 3. Build with Foundation Utilities
+```rust
+// build.rs - Use foundation build functions
+use server::build::generate_routes;
+use pages::build::generate_pages;
+use core_lib::build::process_configuration;
+
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Use foundation build utilities
+    process_configuration("config/")?;
+    generate_routes("content/routes/")?;
+    generate_pages("content/")?;
+    Ok(())
+}
+```
+
+### 4. Create UI with Foundation Components
+```rust
+// Use foundation components and pages
+use components::{
+    navigation::{BrandHeader, Footer},
+    content::UnifiedContentCard,
+    ui::SpaLink,
+};
+use pages::{HomePage, AboutPage, ContactPage};
+
+#[component]
+fn App() -> impl IntoView {
+    view! {
+        <BrandHeader brand_name="My App">
+            <SpaLink href="/">"Home"</SpaLink>
+            <SpaLink href="/about">"About"</SpaLink>
+        </BrandHeader>
+        
+        <Routes>
+            <Route path="/" view=HomePage />
+            <Route path="/about" view=AboutPage />
+            <Route path="/contact" view=ContactPage />
+        </Routes>
+        
+        <Footer copyright="© 2024 My Company" />
+    }
+}
+```
+
+## 🏗️ Usage Patterns
+
+### Pattern 1: Direct Import (Simplest)
+Perfect for getting started quickly:
+```rust
+use server::run_server;
+use components::navigation::BrandHeader;
+use pages::HomePage;
+
+// Use foundation functions directly
+run_server().await?;
+```
+
+### Pattern 2: Configuration-Based  
+Customize behavior through configuration:
+```rust
+use server::{run_server_with_config, ServerConfig};
+use core_lib::config::load_app_config;
+
+let app_config = load_app_config("config.toml")?;
+let server_config = ServerConfig::from_app_config(&app_config);
+run_server_with_config(server_config).await?;
+```
+
+### Pattern 3: Modular Composition
+Compose applications from individual foundation functions:
+```rust
+use server::{create_base_app, setup_tracing, serve_custom_app};
+use components::{theme::ThemeProvider, navigation::BrandHeader};
+use pages::{PageGenerator, BlogTemplate};
+
+// Compose your application
+let app = create_base_app()
+    .merge(custom_routes())
+    .layer(custom_middleware());
+    
+serve_custom_app(app, config).await?;
+```
+
+### Pattern 4: Full Integration
+Complete integration across all foundation crates:
+```rust
+use server::{run_server_with_config, ServerConfig};
+use client::{ClientConfig, hydrate_app};
+use components::theme::{ThemeProvider, ThemeConfig};
+use pages::{generate_pages, PageGeneratorConfig};
+use core_lib::{config::AppConfig, i18n::setup_translations};
+use core_types::{ContentItem, User, Route};
+
+// Complete application using all foundation crates
+// See FOUNDATION_INTEGRATION_GUIDE.md for full example
+```

+# Client Foundation Library
+
+Client-side WebAssembly foundation for Rustelo's configuration-driven web applications, built with Leptos and hydration.
+
+## Overview
+
+The client crate transforms your **TOML configuration** into a reactive WebAssembly client application. It provides zero-configuration hydration, client-side routing, and state management - all generated from your configuration files.
+
+> **🎯 Configuration-Driven**: 90% TOML configuration → generated client, 10% custom extensions when needed
+
+## Architecture Pattern (PAP)
+
+### Primary Usage: Configuration → Generated Client (90%)
+
+Your TOML configuration becomes a complete client application:
+
+```toml
+# site/config/routes/en.toml
+[[routes]]
+path = "/dashboard"
+component = "Dashboard" 
+title_key = "dashboard-title"
+description_key = "dashboard-description"
+language = "en"
+enabled = true
+```
+
+**Generated WebAssembly Client:**
+```rust
+// Generated automatically from your TOML configuration
+include!(concat!(env!("OUT_DIR"), "/generated_routes.rs"));
+include!(concat!(env!("OUT_DIR"), "/generated_components.rs"));
+
+// Your app now has:
+// ✅ Hydration for /dashboard route
+// ✅ Reactive component: Dashboard
+// ✅ i18n with dashboard-title/dashboard-description
+// ✅ Client-side navigation
+// ✅ Theme system integration
+```
+
+### Secondary Usage: Extension Patterns (10%)
+
+When configuration isn't sufficient, extend with custom client code:
+
+```rust
+// Custom client behavior for complex interactions
+use client::{hydrate_with_config, ClientConfig, CustomHydrationConfig};
+
+#[wasm_bindgen::prelude::wasm_bindgen]
+pub fn hydrate() {
+    // Foundation handles 90% through configuration
+    let config = ClientConfig::from_generated()
+        // Add 10% custom behavior when needed
+        .with_custom_analytics()
+        .with_advanced_animations()
+        .with_realtime_features();
+        
+    client::hydrate_with_config(config);
+}
+```
+
+## Quick Start Patterns
+
+### Pattern 1: Zero-Config Hydration (Recommended)
+
+Most applications need only configuration, no client code:
+
+```rust
+// In your application's src/main.rs (WASM target)
+use client;
+
+#[wasm_bindgen::prelude::wasm_bindgen]
+pub fn hydrate() {
+    // Hydrates based on your TOML route configuration
+    // Components generated from site/config/routes/*.toml
+    client::hydrate();
+}
+```
+
+**What this provides:**
+- ✅ Automatic hydration for all configured routes
+- ✅ Client-side navigation between configured pages
+- ✅ Reactive i18n from your fluent files
+- ✅ Theme system with CSS custom properties
+- ✅ Authentication state management (if auth feature enabled)
+
+### Pattern 2: Configuration Validation
+
+Validate your TOML configuration during client build:
+
+```rust
+use client::{validate_client_config, ClientConfigError};
+use core_types::RoutesConfig;
+
+fn main() -> Result<(), ClientConfigError> {
+    // Load your route configuration from TOML
+    let toml_content = include_str!("../site/config/routes/en.toml");
+    let routes_config: RoutesConfig = toml::from_str(toml_content)?;
+    
+    // Validate configuration before building WebAssembly
+    validate_client_config(&routes_config)?;
+    
+    println!("✅ Client configuration is valid");
+    println!("📦 Ready to build WebAssembly with {} routes", 
+             routes_config.routes.len());
+    Ok(())
+}
+```
+
+### Pattern 3: Custom Client Extensions
+
+For the 10% case where configuration can't express your needs:
+
+```rust
+use client::{AppComponent, ClientBuilder, HydrationOptions};
+use leptos::prelude::*;
+
+#[wasm_bindgen::prelude::wasm_bindgen]
+pub fn hydrate() {
+    // Foundation provides 90% from configuration
+    let base_app = client::create_configured_app();
+    
+    // Add 10% custom client functionality
+    let custom_app = ClientBuilder::from(base_app)
+        .with_custom_component("Dashboard", || {
+            view! {
+                // Generated base from TOML config
+                <client::GeneratedDashboard />
+                // Plus custom client-side features
+                <RealtimeMetrics />
+                <AdvancedCharts />
+            }
+        })
+        .with_client_side_analytics()
+        .with_service_worker()
+        .build();
+    
+    // Hydrate with both generated + custom functionality
+    leptos::mount::hydrate_body(|| custom_app);
+}
+```
+
+## Configuration-Driven Features
+
+### Route-Based Hydration
+
+Your TOML routes automatically become hydration targets:
+
+```toml
+# site/config/routes/en.toml
+[[routes]]
+path = "/products/{category}/{slug}"
+component = "ProductDetail"
+title_key = "product-title"
+requires_auth = false
+enabled = true
+
+[[routes]]
+path = "/admin/dashboard"
+component = "AdminDashboard"
+requires_auth = true
+enabled = true
+```
+
+**Generated Client Behavior:**
+```rust
+// Automatically generated from your TOML
+fn handle_route_hydration(path: &str) {
+    match resolve_configured_route(path) {
+        Some(RouteInfo { component: ProductDetail, requires_auth: false, .. }) => {
+            hydrate_product_detail_component(path);
+        }
+        Some(RouteInfo { component: AdminDashboard, requires_auth: true, .. }) => {
+            if user_is_authenticated() {
+                hydrate_admin_dashboard_component(path);
+            } else {
+                redirect_to_login();
+            }
+        }
+        None => hydrate_not_found_component(path),
+    }
+}
+```
+
+### Content-Type Integration
+
+Your `content-kinds.toml` drives client-side content handling:
+
+```toml
+# content/content-kinds.toml
+[blog]
+title = "Blog Posts"
+directory = "blog" 
+features = ["categories", "tags", "comments", "search"]
+client_features = ["infinite-scroll", "live-search", "social-sharing"]
+
+[documentation]
+title = "Documentation"
+directory = "docs"
+features = ["toc", "search", "versioning"]
+client_features = ["collapsible-nav", "keyboard-shortcuts"]
+```
+
+**Generated Client Features:**
+```rust
+// Blog posts get client-side enhancements automatically
+impl BlogPostClient {
+    // Generated from content-kinds.toml client_features
+    fn enable_infinite_scroll(&self) { /* ... */ }
+    fn enable_live_search(&self) { /* ... */ }
+    fn enable_social_sharing(&self) { /* ... */ }
+}
+
+// Documentation gets different client features
+impl DocumentationClient {
+    // Generated from different client_features configuration
+    fn enable_collapsible_nav(&self) { /* ... */ }
+    fn enable_keyboard_shortcuts(&self) { /* ... */ }
+}
+```
+
+### Theme System Integration
+
+Themes configured in TOML become CSS custom properties:
+
+```toml
+# site/config/theme.toml
+[themes.light]
+primary = "#3B82F6"
+background = "#FFFFFF"
+text = "#1F2937"
+
+[themes.dark]
+primary = "#60A5FA"
+background = "#111827" 
+text = "#F9FAFB"
+```
+
+**Generated Client Theme System:**
+```rust
+// Theme switching generated from TOML configuration
+pub fn apply_theme(theme_name: &str) {
+    let theme_config = get_theme_from_config(theme_name);
+    
+    // Updates CSS custom properties automatically
+    set_css_property("--ds-primary", &theme_config.primary);
+    set_css_property("--ds-bg", &theme_config.background);
+    set_css_property("--ds-text", &theme_config.text);
+    
+    // Persists theme choice in localStorage
+    store_theme_preference(theme_name);
+}
+```
+
+## WebAssembly Integration
+
+### Zero-Config WASM Build
+
+The client crate builds to WebAssembly automatically:
+
+```bash
+# Your routes configuration drives what gets compiled to WASM
+cargo leptos build
+
+# Generated files:
+# - target/site/pkg/client.wasm (your configured app)  
+# - target/site/pkg/client.js (generated bindings)
+# - target/site/client_bg.wasm (optimized binary)
+```
+
+### Bundle Size Optimization
+
+Configuration drives what gets included in the WASM bundle:
+
+```toml
+# Only enabled features are compiled to WASM
+[features]
+default = ["hydrate"]
+auth = ["oauth2", "jwt"]
+analytics = ["tracking", "metrics"] 
+performance = ["lazy-loading", "code-splitting"]
+```
+
+**Generated Bundle Strategy:**
+- **Base bundle**: Routes + components from TOML configuration
+- **Feature bundles**: Only enabled features (auth, analytics, etc.)
+- **Lazy bundles**: Route-based code splitting for large applications
+- **Shared chunks**: Common dependencies across generated components
+
+## Hydration System
+
+### SSR-to-Client Handoff
+
+The client seamlessly takes over from server-rendered HTML:
+
+```html
+<!-- Server renders this (from your TOML config) -->
+<div id="app" data-leptos-config="...">
+  <header><!-- Navigation from routes configuration --></header>
+  <main><!-- Page content from component configuration --></main>
+  <footer><!-- Footer from layout configuration --></footer>
+</div>
+```
+
+```rust
+// Client hydrates this automatically
+#[wasm_bindgen::prelude::wasm_bindgen] 
+pub fn hydrate() {
+    // Reads data-leptos-config to understand server state
+    // Hydrates components based on route configuration
+    // Activates client-side routing for configured routes
+    client::hydrate();
+}
+```
+
+### Hydration Debugging
+
+Built-in debugging for development:
+
+```rust
+use client::hydration;
+
+#[cfg(debug_assertions)]
+fn debug_hydration() {
+    // Shows which components are being hydrated
+    hydration::enable_debug_logging();
+    
+    // Validates server-client state consistency
+    hydration::validate_state_consistency(); 
+    
+    // Reports hydration performance metrics
+    hydration::report_performance_metrics();
+}
+```
+
+## Client State Management
+
+### Configuration-Driven State
+
+Your TOML configuration determines what state is managed:
+
+```toml
+# site/config/client-state.toml
+[global_state]
+theme = { type = "persisted", default = "light" }
+language = { type = "reactive", default = "en" } 
+auth = { type = "secure", default = "unauthenticated" }
+
+[page_state.dashboard]
+filters = { type = "local", default = {} }
+sort_order = { type = "persisted", default = "date_desc" }
+```
+
+**Generated State Management:**
+```rust
+// State providers generated from configuration
+#[component]
+pub fn StateProviders(children: Children) -> impl IntoView {
+    view! {
+        // Generated from global_state configuration
+        <ThemeProvider default="light" persisted=true>
+            <LanguageProvider default="en" reactive=true>
+                <AuthProvider default="unauthenticated" secure=true>
+                    {children()}
+                </AuthProvider>
+            </LanguageProvider>
+        </ThemeProvider>
+    }
+}
+```
+
+### Reactive i18n Integration
+
+Language switching triggers reactive updates:
+
+```rust
+// Generated from your fluent files and route configuration  
+use client::i18n::{use_i18n, switch_language};
+
+#[component] 
+pub fn LanguageSwitcher() -> impl IntoView {
+    let i18n = use_i18n(); // Connected to route configuration
+    
+    view! {
+        <select on:change=move |ev| {
+            let new_lang = event_target_value(&ev);
+            // Updates route, reloads content, persists choice
+            switch_language(&new_lang);
+        }>
+            // Options generated from available fluent files
+            <option value="en">English</option>
+            <option value="es">Español</option>
+            <option value="fr">Français</option>
+        </select>
+    }
+}
+```
+
+## Extension Patterns
+
+### Custom Component Integration
+
+Extend generated components with custom behavior:
+
+```rust
+use client::extensions::{ComponentExtension, extend_component};
+
+// Extend a generated component with custom client functionality
+#[component]
+pub fn ExtendedDashboard() -> impl IntoView {
+    // Get the base component from TOML configuration
+    let base_dashboard = client::get_generated_component("Dashboard");
+    
+    // Add custom client-side features
+    let (realtime_data, _) = create_signal(Vec::new());
+    
+    // Custom WebSocket connection for real-time updates
+    create_effect(move |_| {
+        establish_websocket_connection("wss://api.example.com/dashboard");
+    });
+    
+    view! {
+        // Base component (90% from configuration)
+        {base_dashboard}
+        
+        // Custom extensions (10% when needed)
+        <RealtimeMetricsPanel data=realtime_data />
+        <AdvancedCharting />
+        <CustomNotifications />
+    }
+}
+```
+
+### Build-Time Extensions
+
+Extend the build system for custom client generation:
+
+```rust
+// In your build.rs
+use client::build_extensions::{ClientBuildExtension, register_extension};
+
+fn main() -> Result<(), Box<dyn std::error::Error>> {
+    // Foundation generates 90% from TOML configuration
+    client::generate_from_configuration()?;
+    
+    // Add 10% custom build-time generation
+    register_extension(CustomDashboardExtension)?;
+    register_extension(RealtimeComponentsExtension)?;
+    
+    Ok(())
+}
+
+struct CustomDashboardExtension;
+
+impl ClientBuildExtension for CustomDashboardExtension {
+    fn generate_code(&self) -> Result<String, String> {
+        Ok(r#"
+        // Custom generated client code
+        #[component]
+        pub fn CustomDashboard() -> impl IntoView {
+            view! { /* custom dashboard implementation */ }
+        }
+        "#.to_string())
+    }
+}
+```
+
+## Performance Optimization
+
+### Configuration-Based Optimization
+
+Performance features enabled through configuration:
+
+```toml
+# site/config/performance.toml
+[client_optimization]
+bundle_splitting = true
+lazy_loading = true
+preload_critical = true
+tree_shaking = true
+compression = "gzip"
+
+[wasm_optimization]
+size_optimization = "aggressive"
+debug_symbols = false
+lto = true
+panic_strategy = "abort"
+```
+
+**Generated Optimization Strategy:**
+```rust
+// Build configuration drives WASM optimization
+[profile.release]
+lto = true                    # From wasm_optimization.lto
+panic = "abort"              # From wasm_optimization.panic_strategy
+codegen-units = 1           # From size_optimization = "aggressive"
+opt-level = "s"             # Size optimization
+
+// Runtime optimization based on client_optimization
+lazy_static! {
+    static ref PRELOAD_ROUTES: Vec<&'static str> = vec![
+        "/dashboard",   // From preload_critical configuration
+        "/profile",     // High-traffic routes from analytics
+    ];
+}
+```
+
+### Route-Based Code Splitting
+
+TOML routes automatically generate code splits:
+
+```toml
+[[routes]]
+path = "/admin/*"
+component = "AdminSection"  
+lazy_load = true           # Generates separate WASM chunk
+
+[[routes]] 
+path = "/*"
+component = "PublicSection"
+lazy_load = false          # Included in main bundle
+```
+
+**Generated Code Splitting:**
+```rust
+// Automatically generated lazy loading
+async fn load_admin_component() -> Result<AdminComponent, LoadError> {
+    // Loads admin.wasm chunk only when needed
+    let module = wasm_bindgen_futures::JsFuture::from(
+        js_sys::eval("import('./chunks/admin.wasm')")
+    ).await?;
+    
+    Ok(AdminComponent::from_module(module))
+}
+```
+
+## Browser Integration
+
+### Web APIs Access
+
+Safe WebAssembly access to browser APIs:
+
+```rust
+use client::web_apis::{LocalStorage, SessionStorage, Notifications, Location};
+
+// Safe wrappers generated for each configured feature
+#[component]
+pub fn ClientFeatures() -> impl IntoView {
+    let storage = LocalStorage::new(); // Type-safe localStorage wrapper
+    let notifications = Notifications::new(); // Permission handling
+    let location = Location::new(); // URL manipulation
+    
+    // All browser APIs are safely wrapped for WASM usage
+    view! {
+        <button on:click=move |_| {
+            storage.set("theme", "dark").unwrap();
+            notifications.show("Theme changed").unwrap();
+            location.reload().unwrap();
+        }>
+            "Change Theme"
+        </button>
+    }
+}
+```
+
+### Service Worker Integration
+
+Optional service worker for offline functionality:
+
+```toml
+# site/config/pwa.toml
+[service_worker]
+enabled = true
+cache_routes = ["all"]  # Cache all configured routes
+offline_fallbacks = true
+background_sync = true
+```
+
+**Generated Service Worker:**
+```javascript
+// Generated from your route configuration  
+const CACHE_ROUTES = [
+    '/dashboard',    // From your routes TOML
+    '/profile',      // All enabled routes cached
+    '/settings'      // Automatically included
+];
+
+// Routes become offline-available automatically
+self.addEventListener('fetch', event => {
+    if (CACHE_ROUTES.includes(url.pathname)) {
+        event.respondWith(
+            caches.match(event.request)
+                .then(response => response || fetch(event.request))
+        );
+    }
+});
+```
+
+## Testing Integration
+
+### Configuration-Based Testing
+
+Test your TOML configuration directly:
+
+```rust
+#[cfg(test)]
+mod client_config_tests {
+    use super::*;
+    use client::testing::{mock_hydration, validate_routes};
+    
+    #[test]
+    fn test_route_configuration() {
+        let routes_config = load_test_config("routes/en.toml");
+        
+        // Validate all routes are properly configured
+        let validation = validate_routes(&routes_config);
+        assert!(validation.is_ok());
+        
+        // Test hydration for each configured route
+        for route in &routes_config.routes {
+            let result = mock_hydration(&route.path);
+            assert!(result.is_ok(), "Failed to hydrate route: {}", route.path);
+        }
+    }
+    
+    #[test] 
+    fn test_client_state_management() {
+        let state_config = load_test_config("client-state.toml");
+        
+        // Validate state providers work correctly
+        let providers = create_state_providers(&state_config);
+        assert!(providers.theme_provider.is_some());
+        assert!(providers.i18n_provider.is_some());
+    }
+}
+```
+
+### Component Testing in WASM
+
+Test generated components in WebAssembly environment:
+
+```rust
+use wasm_bindgen_test::*;
+use client::testing::WasmTestHarness;
+
+wasm_bindgen_test_configure!(run_in_browser);
+
+#[wasm_bindgen_test]
+async fn test_dashboard_hydration() {
+    let harness = WasmTestHarness::new();
+    
+    // Test hydration of configured component
+    let dashboard = harness.hydrate_component("Dashboard", "/dashboard").await;
+    assert!(dashboard.is_ok());
+    
+    // Test client-side navigation
+    let result = harness.navigate_to("/profile").await;
+    assert!(result.is_ok());
+    
+    // Test reactive state updates
+    harness.update_theme("dark").await;
+    let theme = harness.get_current_theme().await;
+    assert_eq!(theme, "dark");
+}
+```

+# Client Hydration Guide
+
+Comprehensive guide to Rustelo's configuration-driven client hydration system.
+
+## Overview
+
+Rustelo's client hydration transforms server-rendered HTML into a fully reactive WebAssembly application. The hydration process is **90% configuration-driven** from your TOML files, with **10% custom extension** capabilities for complex requirements.
+
+## Core Hydration Flow
+
+### 1. Configuration-Driven Hydration (90% Use Case)
+
+Your TOML configuration drives the entire hydration process:
+
+```toml
+# site/config/routes/en.toml
+[[routes]]
+path = "/dashboard"
+component = "Dashboard"
+title_key = "dashboard-title"
+language = "en"
+enabled = true
+hydration_priority = "high"
+
+[[routes]]
+path = "/profile"
+component = "Profile"
+title_key = "profile-title"
+language = "en" 
+enabled = true
+hydration_priority = "normal"
+```
+
+**Generated Hydration Code:**
+```rust
+// Generated from your TOML configuration
+#[wasm_bindgen]
+pub fn hydrate() {
+    // Read server-rendered page data
+    let page_data = extract_server_state();
+    let current_path = get_current_path();
+    
+    // Route resolution from TOML configuration
+    match resolve_configured_route(&current_path) {
+        Some(route_info) => {
+            hydrate_configured_component(&route_info, page_data);
+        }
+        None => {
+            hydrate_not_found_component(&current_path);
+        }
+    }
+    
+    // Activate client-side routing for all configured routes
+    activate_client_routing();
+}
+```
+
+### 2. Server-Client State Handoff
+
+The hydration system seamlessly transitions from server state to client state:
+
+```html
+<!-- Server-rendered HTML with embedded state -->
+<div id="app" data-leptos-hydration="true">
+  <script type="application/json" id="__LEPTOS_STATE__">
+    {
+      "route": "/dashboard",
+      "component": "Dashboard", 
+      "props": { "user_id": "123" },
+      "i18n_data": { "language": "en", "messages": {...} },
+      "theme": "light"
+    }
+  </script>
+  
+  <!-- Server-rendered component HTML -->
+  <div class="dashboard-container">
+    <h1>Dashboard</h1>
+    <!-- ... more server-rendered content -->
+  </div>
+</div>
+```
+
+```rust
+// Client hydration reads and uses server state
+#[wasm_bindgen]
+pub fn hydrate() {
+    let server_state = read_embedded_state();
+    
+    // Hydrate with exact server state to prevent mismatches
+    leptos::mount::hydrate_body(move || {
+        view! {
+            <AppComponent 
+                initial_route=server_state.route
+                initial_props=server_state.props
+                initial_theme=server_state.theme
+            />
+        }
+    });
+}
+```
+
+## Hydration Patterns
+
+### Pattern 1: Zero-Config Hydration
+
+Most common pattern - pure configuration-driven:
+
+```rust
+use client;
+
+#[wasm_bindgen]
+pub fn hydrate() {
+    // Reads your TOML routes and hydrates automatically
+    client::hydrate();
+}
+```
+
+**What this provides:**
+- ✅ Automatic component hydration for all configured routes
+- ✅ State management providers (theme, i18n, auth)
+- ✅ Client-side routing activation
+- ✅ Error boundary setup
+- ✅ Development debugging tools
+
+### Pattern 2: Hydration with Validation
+
+Validate configuration before hydration:
+
+```rust
+use client::{hydrate_with_validation, HydrationConfig};
+
+#[wasm_bindgen]
+pub fn hydrate() {
+    let config = HydrationConfig::from_toml_files()
+        .validate_routes()
+        .validate_components()
+        .validate_i18n_keys();
+    
+    match config.build() {
+        Ok(validated_config) => {
+            client::hydrate_with_config(validated_config);
+        }
+        Err(validation_errors) => {
+            console::error!("Hydration validation failed: {:?}", validation_errors);
+            client::hydrate_with_fallback();
+        }
+    }
+}
+```
+
+### Pattern 3: Custom Hydration Extensions (10% Case)
+
+When you need custom hydration behavior:
+
+```rust
+use client::{HydrationBuilder, CustomHydrationHooks};
+
+#[wasm_bindgen]
+pub fn hydrate() {
+    let hooks = CustomHydrationHooks::builder()
+        .with_pre_hydration(|| {
+            // Custom initialization before hydration
+            setup_analytics_tracking();
+            initialize_performance_monitoring();
+        })
+        .with_post_hydration(|| {
+            // Custom setup after hydration
+            activate_service_worker();
+            setup_keyboard_shortcuts();
+        })
+        .with_component_hydration(|component_name, element| {
+            // Custom per-component hydration logic
+            match component_name {
+                "Dashboard" => setup_realtime_dashboard(element),
+                "Chart" => initialize_chart_interactions(element),
+                _ => {} // Use default hydration
+            }
+        })
+        .build();
+    
+    client::hydrate_with_hooks(hooks);
+}
+```
+
+## Hydration Lifecycle
+
+### Phase 1: Initialization
+
+```rust
+// 1. WebAssembly module loads
+wasm_bindgen::start();
+
+// 2. Panic hook setup for debugging
+console_error_panic_hook::set_once();
+
+// 3. Read server-embedded configuration
+let server_config = read_leptos_state();
+let route_config = load_toml_routes();
+
+// 4. Validate server-client consistency
+validate_state_consistency(&server_config, &route_config)?;
+```
+
+### Phase 2: Component Hydration
+
+```rust
+// 5. Resolve current route from URL
+let current_path = window().location().pathname();
+let route_info = resolve_route(&current_path, &route_config)?;
+
+// 6. Hydrate matching component
+match route_info.component {
+    RouteComponent::Dashboard => hydrate_dashboard_component(),
+    RouteComponent::Profile => hydrate_profile_component(),
+    RouteComponent::Settings => hydrate_settings_component(),
+    _ => hydrate_not_found_component(),
+}
+
+// 7. Activate reactive signals and effects
+activate_component_reactivity();
+```
+
+### Phase 3: System Activation
+
+```rust
+// 8. Setup state providers from configuration
+setup_theme_provider(&route_config.theme);
+setup_i18n_provider(&route_config.i18n);
+setup_auth_provider(&route_config.auth);
+
+// 9. Activate client-side routing
+let router = create_configured_router(&route_config.routes);
+activate_client_routing(router);
+
+// 10. Setup cross-component communication
+setup_event_bus();
+
+// 11. Mark hydration as complete
+mark_hydration_complete();
+```
+
+## Hydration Debugging
+
+### Development Debug Mode
+
+Enable comprehensive hydration debugging:
+
+```rust
+#[cfg(debug_assertions)]
+use client::debug::{HydrationDebugger, DebugLevel};
+
+#[wasm_bindgen]
+pub fn hydrate() {
+    let debugger = HydrationDebugger::new()
+        .with_level(DebugLevel::Verbose)
+        .with_performance_tracking(true)
+        .with_state_validation(true)
+        .with_component_tracing(true);
+    
+    client::hydrate_with_debugger(debugger);
+}
+```
+
+**Debug Output:**
+```
+🔍 [HYDRATION] Starting hydration process
+📊 [PERFORMANCE] Hydration start time: 1634567890123

+🛣️ [ROUTER] Activating client-side routing for 5 routes
+✨ [COMPLETE] Hydration completed in 234ms
+```
+
+### Hydration Error Handling
+
+Graceful error handling for hydration issues:
+
+```rust
+use client::{HydrationError, HydrationRecovery};
+
+#[wasm_bindgen]
+pub fn hydrate() {
+    match client::hydrate_with_recovery() {
+        Ok(()) => {
+            console::log!("✅ Hydration successful");
+        }
+        Err(HydrationError::StateMismatch { server, client }) => {
+            console::warn!("⚠️ State mismatch detected");
+            console::debug!("Server state: {:?}", server);
+            console::debug!("Client state: {:?}", client);
+            
+            // Attempt recovery
+            client::recover_from_state_mismatch(server, client);
+        }
+        Err(HydrationError::ComponentNotFound { component }) => {
+            console::error!("❌ Component not found: {}", component);
+            
+            // Fall back to generic component
+            client::hydrate_with_fallback_component();
+        }
+        Err(HydrationError::ConfigurationError { message }) => {
+            console::error!("🔧 Configuration error: {}", message);
+            
+            // Fall back to minimal hydration
+            client::hydrate_minimal();
+        }
+    }
+}
+```
+
+## Performance Optimization
+
+### Hydration Priority
+
+Configure hydration priority in TOML:
+
+```toml
+# High priority - hydrate immediately
+[[routes]]
+path = "/dashboard"
+component = "Dashboard"
+hydration_priority = "critical"
+preload_data = true
+
+# Normal priority - hydrate after critical
+[[routes]]
+path = "/profile"
+component = "Profile"
+hydration_priority = "normal"
+
+# Low priority - hydrate lazily
+[[routes]]
+path = "/settings"
+component = "Settings"
+hydration_priority = "lazy"
+defer_hydration = true
+```
+
+**Generated Hydration Strategy:**
+```rust
+// Prioritized hydration based on configuration
+async fn hydrate_with_priorities() {
+    // Phase 1: Critical components (blocking)
+    hydrate_critical_components().await;
+    
+    // Phase 2: Normal components (non-blocking)
+    spawn_local(async {
+        hydrate_normal_components().await;
+    });
+    
+    // Phase 3: Lazy components (on-demand)
+    setup_lazy_hydration_triggers();
+}
+```
+
+### Bundle Splitting for Hydration
+
+Route-based code splitting:
+
+```toml
+# Main bundle
+[[routes]]
+path = "/"
+component = "Home"
+bundle = "main"
+
+[[routes]]
+path = "/dashboard"
+component = "Dashboard" 
+bundle = "main"
+
+# Admin bundle (lazy-loaded)
+[[routes]]
+path = "/admin/*"
+component = "AdminSection"
+bundle = "admin"
+lazy_load = true
+
+# Feature bundles
+[[routes]]
+path = "/analytics"
+component = "Analytics"
+bundle = "analytics"
+lazy_load = true
+```
+
+**Generated Loading Strategy:**
+```rust
+// Main bundle hydrates immediately
+hydrate_main_bundle();
+
+// Lazy bundles load on demand
+async fn navigate_to_admin() {
+    let admin_module = load_bundle("admin").await?;
+    hydrate_bundle_components(admin_module).await?;
+}
+```
+
+## Advanced Hydration Patterns
+
+### Progressive Hydration
+
+Hydrate components progressively based on viewport:
+
+```toml
+[[routes]]
+path = "/dashboard"
+component = "Dashboard"
+hydration_strategy = "progressive"
+viewport_priority = true
+```
+
+```rust
+// Progressive hydration implementation
+#[component]
+pub fn ProgressivelyHydratedDashboard() -> impl IntoView {
+    let (is_in_viewport, set_is_in_viewport) = create_signal(false);
+    let dashboard_ref = create_node_ref::<html::Div>();
+    
+    // Hydrate when component enters viewport
+    create_effect(move |_| {
+        if let Some(element) = dashboard_ref.get() {
+            let intersection_observer = create_intersection_observer(
+                move |entries| {
+                    for entry in entries {
+                        if entry.is_intersecting() {
+                            set_is_in_viewport.set(true);
+                        }
+                    }
+                }
+            );
+            
+            intersection_observer.observe(&element);
+        }
+    });
+    
+    view! {
+        <div node_ref=dashboard_ref>
+            {move || {
+                if is_in_viewport.get() {
+                    view! { <FullDashboardComponent /> }.into_any()
+                } else {
+                    view! { <DashboardPlaceholder /> }.into_any()
+                }
+            }}
+        </div>
+    }
+}
+```
+
+### Hydration with Service Workers
+
+Offline-capable hydration:
+
+```toml
+[service_worker]
+enabled = true
+cache_hydration_data = true
+offline_fallback = true
+```
+
+```rust
+// Service worker integration for hydration
+#[wasm_bindgen]
+pub fn hydrate() {
+    spawn_local(async {
+        // Try to get cached hydration data
+        if let Ok(cached_data) = get_cached_hydration_data().await {
+            hydrate_with_cached_data(cached_data);
+        } else if navigator.on_line() {
+            // Online: normal hydration
+            client::hydrate();
+        } else {
+            // Offline: fallback hydration
+            client::hydrate_offline_mode();
+        }
+    });
+}
+```
+
+## Testing Hydration
+
+### Hydration Tests
+
+Test hydration behavior:
+
+```rust
+#[cfg(test)]
+mod hydration_tests {
+    use super::*;
+    use wasm_bindgen_test::*;
+    
+    wasm_bindgen_test_configure!(run_in_browser);
+    
+    #[wasm_bindgen_test]
+    async fn test_dashboard_hydration() {
+        // Setup server-rendered HTML
+        let server_html = create_server_rendered_html("/dashboard");
+        document().body().unwrap().set_inner_html(&server_html);
+        
+        // Test hydration
+        let result = client::hydrate_route("/dashboard").await;
+        assert!(result.is_ok());
+        
+        // Verify component is interactive
+        let dashboard = document()
+            .query_selector(".dashboard-container")
+            .unwrap()
+            .unwrap();
+        
+        // Test that click events work (hydration successful)
+        let button = dashboard
+            .query_selector("button")
+            .unwrap()
+            .unwrap();
+        
+        button.click();
+        
+        // Verify reactive state updated
+        assert_eq!(get_dashboard_state().active_tab, "metrics");
+    }
+    
+    #[wasm_bindgen_test]
+    async fn test_hydration_error_recovery() {
+        // Create mismatched server state
+        set_server_state("dashboard", serde_json::json!({
+            "version": "1.0",
+            "data": {"user_id": "123"}
+        }));
+        
+        // Simulate client with different version
+        let result = client::hydrate_with_validation().await;
+        
+        // Should recover gracefully
+        assert!(result.is_ok());
+        assert_eq!(get_hydration_status(), HydrationStatus::RecoveredFromMismatch);
+    }
+}
+```
+
+### Hydration Performance Tests
+
+Monitor hydration performance:
+
+```rust
+#[wasm_bindgen_test]
+async fn test_hydration_performance() {
+    let start_time = js_sys::Date::now();
+    
+    client::hydrate().await;
+    
+    let hydration_time = js_sys::Date::now() - start_time;
+    
+    // Hydration should complete within performance budget
+    assert!(hydration_time < 500.0, "Hydration took {}ms, expected < 500ms", hydration_time);
+    
+    // Verify all critical components hydrated
+    assert!(is_component_hydrated("Navigation"));
+    assert!(is_component_hydrated("MainContent"));
+    assert!(is_component_hydrated("Footer"));
+}
+```
+
+## Best Practices
+
+### 1. Configuration-First Approach
+- Use TOML configuration for 90% of hydration behavior
+- Only add custom hydration code for complex requirements
+- Validate configuration at build time
+
+### 2. Performance Optimization
+- Use hydration priorities to control loading order
+- Implement progressive hydration for large applications
+- Monitor hydration performance in production
+
+### 3. Error Handling
+- Always include fallback hydration strategies
+- Implement graceful degradation for hydration failures
+- Log hydration errors for debugging
+
+### 4. Development Experience
+- Enable debug mode during development
+- Use comprehensive logging for troubleshooting
+- Test hydration behavior across different scenarios
+
+### 5. State Consistency
+- Ensure server and client render identical HTML
+- Validate state consistency during hydration
+- Handle state mismatches gracefully
+
+## Common Issues and Solutions
+
+### Issue: Hydration Mismatches
+
+**Symptom:** Console errors about DOM structure differences
+
+**Solution:**
+```rust
+// Ensure server and client render identical content
+#[component]
+pub fn ConsistentComponent() -> impl IntoView {
+    // Use server-safe default values
+    let (client_only_state, set_client_only_state) = create_signal(None);
+    
+    // Initialize client state after hydration
+    create_effect(move |_| {
+        if !is_server_rendering() {
+            set_client_only_state.set(Some(initialize_client_state()));
+        }
+    });
+    
+    view! {
+        <div>
+            // Always render server-safe content first
+            <h1>"Title"</h1>
+            
+            // Client-only features after hydration
+            {move || {
+                if let Some(state) = client_only_state.get() {
+                    view! { <ClientOnlyFeatures state=state /> }.into_any()
+                } else {
+                    view! { <div></div> }.into_any()
+                }
+            }}
+        </div>
+    }
+}
+```
+
+### Issue: Slow Hydration
+
+**Symptom:** Long time to interactive
+
+**Solution:**
+```toml
+# Configure progressive hydration
+[hydration]
+strategy = "progressive"
+critical_components = ["Navigation", "MainContent"]
+defer_non_critical = true
+viewport_based = true
+```
+
+### Issue: Bundle Size
+
+**Symptom:** Large WebAssembly bundle affecting hydration speed
+
+**Solution:**
+```toml
+# Enable code splitting
+[optimization]
+bundle_splitting = true
+tree_shaking = true
+lazy_loading = true
+
+# Route-based splitting
+[[routes]]
+path = "/admin/*"
+bundle = "admin"
+lazy_load = true
+```
+
+This guide covers the essential patterns and best practices for Rustelo's configuration-driven hydration system. The 90/10 rule applies: use TOML configuration for standard hydration needs, and custom code only for complex requirements that configuration can't express.

+//! - **⚡ Reactive UI** - Built with Leptos for fast, reactive user interfaces
+//! - **🎨 Component System** - Reusable UI components with props and state
+//! - **🌐 Internationalization** - Multi-language support with fluent
+//! - **🔐 Authentication** - Complete auth flow with JWT and OAuth2
+//! - **📱 Responsive Design** - Mobile-first design with Tailwind CSS
+//! - **🚀 WebAssembly** - High-performance client-side rendering
+//!
+//! ## Architecture
+//!
+//! The client is organized into several key modules:
+//!
+//! - [`app`] - Minimal hydration component for WebAssembly
+//! - [`components`] - Reusable UI components and forms
+//! - [`pages`] - Individual page components (Home, About, etc.)
+//! - [`auth`] - Authentication components and context
+//! - [`state`] - Global state management and themes
+//! - [`i18n`] - Internationalization and language support
+//! - [`utils`] - Client-side utilities and helpers
+//!
+//! ## Quick Start
+//!
+//! ```rust,ignore
+//! use rustelo_client::app::App;
+//! use leptos::prelude::*;
+//!
+//! // Hydrate SSR content with client reactivity
+//! leptos::mount::hydrate_body(|| view! { <App /> });
+//! ```
+//!
+//! ## Component Usage
+//!
+//! ### Authentication Components
+//!
+//! ```rust,ignore
+//! use rustelo_client::auth::{AuthProvider, LoginForm};
+//! use leptos::prelude::*;
+//!
+//! view! {
+//!   <AuthProvider>
+//!     <LoginForm />
+//!   </AuthProvider>
+//! }
+//! ```
+//!
+//! ### Form Components
+//!
+//! ```rust,ignore
+//! use rustelo_client::rustelo_components::{ContactForm, SupportForm};
+//! use leptos::prelude::*;
+//!
+//! view! {
+//!   <ContactForm />
+//!   <SupportForm />
+//! }
+//! ```
+//!
+//! ## State Management
+//!
+//! ### Theme Management
+//!
+//! ```rust,ignore
+//! use rustelo_client::state::theme::{ThemeProvider, use_theme_state, Theme};
+//! use leptos::prelude::*;
+//!
+//! #[component]
+//! fn MyComponent() -> impl IntoView {
+//!   let theme_state = use_theme_state();
+//!
+//!   view! {
+//!     <button on:click=move |_| theme_state.toggle()>
+//!       "Toggle Theme"
+//!     </button>
+//!   }
+//! }
+//! ```
+//!
+//! ## Internationalization
+//!
+//! ```rust,ignore
+//! use rustelo_client::i18n::{I18nProvider, use_i18n};
+//! use leptos::prelude::*;
+//!
+//! #[component]
+//! fn MyComponent() -> impl IntoView {
+//!   let i18n = use_i18n();
+//!
+//!   view! {
+//!     <p>{i18n.t("welcome_message")}</p>
+//!   }
+//! }
+//! ```
+//!
+//! ## WebAssembly Integration
+//!
+//! The client is designed to run efficiently in WebAssembly environments:
+//!
+//! - **Small Bundle Size** - Optimized for fast loading
+//! - **Memory Efficient** - Careful memory management
+//! - **Browser APIs** - Safe access to web APIs through web-sys
+//! - **Error Handling** - Comprehensive error boundaries
+//!
+//! ## Development
+//!
+//! ### Building
+//!
+//! ```bash
+//! # Development build
+//! cargo build --target wasm32-unknown-unknown
+//!
+//! # Production build
+//! cargo build --release --target wasm32-unknown-unknown
+//!
+//! # Using cargo-leptos
+//! cargo leptos build
+//! ```
+//!
+//! ### Testing
+//!
+//! ```bash
+//! # Run tests
+//! cargo test
+//!
+//! # Run tests in browser
+//! wasm-pack test --headless --chrome
+//! ```
+//!
+//! ## Performance
+//!
+//! Optimized for performance with:
+//!
+//! - **Lazy Loading** - Components loaded on demand
+//! - **Virtual DOM** - Efficient rendering with fine-grained reactivity
+//! - **Code Splitting** - Reduced initial bundle size
+//! - **Caching** - Smart caching of static assets
+//!
+//! ## Browser Support
+//!
+//! - **Modern Browsers** - Chrome 80+, Firefox 72+, Safari 13.1+, Edge 80+
+//! - **WebAssembly** - Required for optimal performance
+//! - **JavaScript Fallback** - Graceful degradation where possible

+# Components Foundation Library
+
+Reusable UI components for Rustelo web applications built with Leptos.
+
+## Quick Start
+
+### Basic Component Usage
+```rust
+use components::{
+    navigation::{BrandHeader, Footer, NavMenu},
+    content::{UnifiedContentCard, ContentManager},
+    ui::{SpaLink, MobileMenu},
+    theme::{ThemeProvider, DarkModeToggle},
+};
+
+#[component]
+fn MyApp() -> impl IntoView {
+    view! {
+        <ThemeProvider>
+            <BrandHeader />
+            <main>
+                <UnifiedContentCard title="Hello World" />
+            </main>
+            <Footer />
+        </ThemeProvider>
+    }
+}
+```
+
+### Component Sets
+```rust
+// Import entire component categories
+use components::navigation::*;  // All navigation components
+use components::forms::*;       // All form components  
+use components::layout::*;      // All layout components
+```
+
+### Custom Theming
+```rust
+use components::theme::{ThemeProvider, ThemeConfig};
+
+let theme = ThemeConfig::builder()
+    .primary_color("#007acc")
+    .font_family("Inter")
+    .build();
+
+view! {
+    <ThemeProvider config=theme>
+        <App />
+    </ThemeProvider>
+}
+```
+
+## Usage Patterns
+
+### 1. Direct Import (Simplest)
+Import individual components as needed:
+```rust
+use components::navigation::BrandHeader;
+use components::content::UnifiedContentCard;
+```
+
+### 2. Category Import
+Import entire component categories:
+```rust
+use components::forms::*;
+use components::navigation::*;
+```
+
+### 3. Themed Components
+Use components with custom theming:
+```rust
+use components::theme::{ThemeProvider, use_theme};
+
+#[component] 
+fn CustomComponent() -> impl IntoView {
+    let theme = use_theme();
+    // Use theme.primary_color, theme.font_size, etc.
+}
+```
+
+### 4. Extended Components
+Extend foundation components with custom functionality:
+```rust
+use components::content::UnifiedContentCard;
+
+#[component]
+fn CustomCard(
+    #[prop(into)] title: String,
+    children: Children,
+) -> impl IntoView {
+    view! {
+        <UnifiedContentCard title=title>
+            <div class="custom-wrapper">
+                {children()}
+            </div>
+        </UnifiedContentCard>
+    }
+}
+```

+# Components Foundation Usage Patterns
+
+## Overview
+The components foundation provides multiple usage patterns to fit different application needs, from simple component imports to complex themed applications.
+
+## Pattern 1: Direct Component Import (Simplest)
+
+**Best for**: Simple applications, specific component needs
+
+```rust
+use components::{
+    navigation::BrandHeader,
+    content::UnifiedContentCard,
+    ui::SpaLink,
+};
+
+#[component]
+fn HomePage() -> impl IntoView {
+    view! {
+        <BrandHeader />
+        <main>
+            <UnifiedContentCard title="Welcome">
+                <p>"Hello World"</p>
+                <SpaLink href="/about">"Learn More"</SpaLink>
+            </UnifiedContentCard>
+        </main>
+    }
+}
+```
+
+**What you get**:
+- Individual components as needed
+- Minimal bundle size
+- Full component functionality
+
+**Customization**: Component props and CSS classes
+
+## Pattern 2: Category Import
+
+**Best for**: Using multiple related components
+
+```rust
+use components::{
+    navigation::*,  // BrandHeader, Footer, NavMenu, etc.
+    content::*,     // All content components
+    ui::*,          // All UI utilities
+};
+
+#[component]
+fn AppLayout() -> impl IntoView {
+    view! {
+        <BrandHeader>
+            <NavMenu />
+        </BrandHeader>
+        
+        <main>
+            <UnifiedContentCard title="Content">
+                <SimpleContentGrid>
+                    // Content items
+                </SimpleContentGrid>
+            </UnifiedContentCard>
+        </main>
+        
+        <Footer />
+    }
+}
+```
+
+**What you get**:
+- All components from specific categories
+- Consistent component families
+- Easy access to related functionality
+
+**Customization**: Mix and match components from different categories
+
+## Pattern 3: Themed Application
+
+**Best for**: Applications with consistent branding and theming
+
+```rust
+use components::{
+    theme::{ThemeProvider, ThemeConfig, use_theme},
+    navigation::*,
+    content::*,
+};
+
+#[component]
+pub fn ThemedApp() -> impl IntoView {
+    let theme_config = ThemeConfig::builder()

+```
+
+**What you get**:
+- Consistent theming across all components
+- Theme context available to custom components
+- Built-in dark/light mode support
+
+**Customization**: Custom theme configuration, theme switching
+
+## Pattern 4: Extended Components
+
+**Best for**: Custom functionality built on foundation components
+
+```rust
+use components::{
+    content::{UnifiedContentCard, ContentManager},
+    ui::SpaLink,
+    theme::use_theme,
+};
+
+// Extend foundation components with custom logic
+#[component]
+pub fn BlogCard(
+    #[prop(into)] title: String,
+    #[prop(into)] excerpt: String,
+    #[prop(into)] slug: String,
+    #[prop(into)] date: String,
+) -> impl IntoView {
+    let theme = use_theme();
+    
+    view! {
+        <UnifiedContentCard title=title>
+            <div class="blog-card-content">
+                <p class="excerpt">{excerpt}</p>
+                <div class="blog-meta">
+                    <span class="date" style=format!("color: {}", theme.text_muted())>
+                        {date}
+                    </span>
+                    <SpaLink href=format!("/blog/{}", slug) class="read-more">
+                        "Read More →"
+                    </SpaLink>
+                </div>
+            </div>
+        </UnifiedContentCard>
+    }
+}
+
+// Create custom component collections
+#[component]
+pub fn BlogGrid(posts: ReadSignal<Vec<BlogPost>>) -> impl IntoView {
+    view! {
+        <div class="blog-grid">
+            <For
+                each=move || posts.get()
+                key=|post| post.id.clone()
+                children=move |post| {
+                    view! {
+                        <BlogCard
+                            title=post.title
+                            excerpt=post.excerpt
+                            slug=post.slug
+                            date=post.published_date
+                        />
+                    }
+                }
+            />
+        </div>
+    }
+}
+```
+
+**What you get**:
+- Custom components built on foundation
+- Reusable component patterns
+- Integration with foundation theming
+
+**Customization**: Full control over extended component behavior
+
+## Pattern 5: Modular Composition
+
+**Best for**: Complex applications with feature-based component organization
+
+```rust

+```
+
+**What you get**:
+- Feature-organized component modules
+- Selective component usage
+- Clean separation of concerns
+
+**Customization**: Module-based customization and feature flags
+
+## Responsive Design Patterns
+
+### Mobile-First Components
+```rust
+use components::{
+    navigation::BrandHeader,
+    ui::{MobileMenu, MobileMenuToggle},
+    theme::use_theme,
+};
+
+#[component]
+pub fn ResponsiveHeader() -> impl IntoView {
+    let (mobile_menu_open, set_mobile_menu_open) = create_signal(false);
+    
+    view! {
+        <BrandHeader>
+            // Desktop navigation
+            <nav class="hidden md:block">
+                <SpaLink href="/">"Home"</SpaLink>
+                <SpaLink href="/about">"About"</SpaLink>
+                <SpaLink href="/contact">"Contact"</SpaLink>
+            </nav>
+            
+            // Mobile menu toggle
+            <div class="md:hidden">
+                <MobileMenuToggle 
+                    is_open=mobile_menu_open
+                    on_toggle=move |_| set_mobile_menu_open.update(|open| *open = !*open)
+                />
+            </div>
+        </BrandHeader>
+        
+        // Mobile menu
+        <MobileMenu 
+            is_open=mobile_menu_open
+            on_close=move |_| set_mobile_menu_open.set(false)
+        >
+            <SpaLink href="/">"Home"</SpaLink>
+            <SpaLink href="/about">"About"</SpaLink>
+            <SpaLink href="/contact">"Contact"</SpaLink>
+        </MobileMenu>
+    }
+}
+```
+
+## Error Handling Patterns
+
+### Component Error Boundaries
+```rust
+use components::{content::UnifiedContentCard, ui::SpaLink};
+
+#[component]
+pub fn SafeContentCard(
+    #[prop(into)] title: String,
+    #[prop(optional)] fallback: Option<View>,
+) -> impl IntoView {
+    let content = create_resource(
+        || (), 
+        |_| async move { load_content().await }
+    );
+    
+    view! {
+        <UnifiedContentCard title=title>
+            <Suspense fallback=|| view! { <div>"Loading..."</div> }>
+                <ErrorBoundary fallback=move |errors| {
+                    match fallback {
+                        Some(fallback_view) => fallback_view,
+                        None => view! {
+                            <div class="error-state">
+                                <p>"Unable to load content"</p>
+                                <SpaLink href="/" class="btn btn-primary">
+                                    "Go Home"
+                                </SpaLink>
+                            </div>
+                        }.into_view(),
+                    }
+                }>
+                    {move || {
+                        content.get()
+                            .map(|result| match result {
+                                Ok(content) => view! { <div>{content}</div> },
+                                Err(_) => view! { <div>"Error loading content"</div> },
+                            })
+                    }}
+                </ErrorBoundary>
+            </Suspense>
+        </UnifiedContentCard>
+    }
+}
+```
+
+## Performance Optimization Patterns
+
+### Lazy Loading Components
+```rust
+use components::{content::ContentManager, ui::SpaLink};
+
+#[component]
+pub fn LazyContentSection(
+    #[prop(into)] section_id: String,
+) -> impl IntoView {
+    let (is_visible, set_is_visible) = create_signal(false);
+    let section_ref = create_node_ref::<html::Div>();
+    
+    // Intersection observer for lazy loading
+    create_effect(move |_| {
+        if let Some(section) = section_ref.get() {
+            let observer = web_sys::IntersectionObserver::new(&wasm_bindgen::Closure::wrap(
+                Box::new(move |entries: js_sys::Array, _observer| {
+                    if entries.length() > 0 {
+                        set_is_visible.set(true);
+                    }
+                }) as Box<dyn Fn(js_sys::Array, web_sys::IntersectionObserver)>
+            ).into_js_value().unchecked_into()).unwrap();
+            
+            observer.observe(&section);
+        }
+    });
+    
+    view! {
+        <div node_ref=section_ref class="lazy-section">
+            {move || {
+                if is_visible.get() {
+                    view! {
+                        <ContentManager 
+                            content_type="section"
+                            filter=section_id.clone()
+                        />
+                    }
+                } else {
+                    view! {
+                        <div class="lazy-placeholder">
+                            "Loading section..."
+                        </div>
+                    }
+                }
+            }}
+        </div>
+    }
+}
+```
+
+## Choosing the Right Pattern
+
+| Need | Pattern | Complexity | Bundle Size | Flexibility |
+|------|---------|------------|-------------|-------------|
+| Single component | Direct Import | Low | Minimal | Low |
+| Related components | Category Import | Low | Small | Medium |
+| Consistent styling | Themed Application | Medium | Medium | Medium |
+| Custom functionality | Extended Components | Medium | Variable | High |
+| Complex apps | Modular Composition | High | Optimized | Maximum |
+
+## Migration Path
+
+1. **Start Simple**: Use direct imports for initial development
+2. **Add Theming**: Introduce ThemeProvider when styling becomes complex
+3. **Create Extensions**: Build custom components as needs grow
+4. **Organize Modularly**: Structure into feature modules for large apps
+
+Each pattern builds on the foundation components, so migration is incremental and non-breaking.

+//! Filter Components Module
+//!
+//! Provides modular filter components that work seamlessly in both
+//! server-side rendering (SSR) and client-side (WASM) environments.
+//!
+//! ## Architecture
+//!
+//! This module follows the project's modular architecture pattern:
+//! - `shared.rs` - Common types and utilities used by both client and server
+//! - `ssr.rs` - Server-side rendering implementations
+//! - `client.rs` - Client-side interactive implementations
+//! - `unified.rs` - Unified components that automatically choose the right implementation
+//!
+//! ## Usage
+//!
+//! Import the unified components for seamless SSR/client compatibility:
+//!
+//! ```rust
+//! use rustelo_components::filter::ContentCategoryFilter};
+//! use leptos::prelude::*;
+//!
