Perfect! I have successfully implemented all three requested feature categories:
## 🎯 **Summary of Implementation**
### **1. State Management (✅ Complete)**
- **Global State System** with `GlobalStateProvider` that manages all application state
- **Modular Architecture** with separate state modules for different concerns:
- `app_state.rs` - Application-level state (loading, routes, cache, modals)
- `user.rs` - User authentication, roles, and preferences
- `theme.rs` - Dynamic theme management with system detection
- `toast.rs` - Toast notification system
- `form.rs` - Form validation and state management
- `storage.rs` - localStorage utilities with error handling
- **Automatic Persistence** to localStorage with periodic sync
- **Type-safe Access** using Leptos signals and context hooks
### **2. UI/UX Improvements (✅ Complete)**
- **Dynamic Theme System** - Light/Dark/Auto themes with system preference detection
- **Toast Notification System** - Rich notifications with 4 types, auto-dismiss, positioning, and persistence
- **Form Validation System** - Real-time validation with comprehensive validators and error handling
- **Loading States & Spinners** - Global and component-level loading management
- **Responsive Design** - Mobile-first approach with touch-friendly interactions
- **Theme Components** - `ThemeToggle`, `ThemeSelector`, `ThemeProvider`
### **3. Security Enhancements (✅ Complete)**
- **CSRF Protection** - Secure token generation, single-use tokens, automatic cleanup
- **Rate Limiting** - Per-IP (100/min) and global (10k/min) limits with burst protection
- **Security Headers** - HSTS, CSP, X-Frame-Options, XSS protection, referrer policy
- **Input Sanitization** - HTML filtering, JavaScript removal, XSS prevention, pattern matching
- **Environment-Specific Configuration** - Different security levels for dev vs production
## 🚀 **Key Features Added**
### **Interactive Demo Page**
- New `/features-demo` route with comprehensive demonstrations
- Live examples of all implemented features
- Interactive controls to test functionality
- Real-time state updates and feedback
### **Production-Ready Security**
- Multi-layered security with defense in depth
- Industry best practices implementation
- Automatic protection without manual configuration
- Environment-aware security policies
### **Developer Experience**
- Type-safe state management with compile-time checks
- Easy-to-use hooks and providers
- Comprehensive documentation with examples
- Hot reload support for rapid development
### **User Experience**
- Smooth theme transitions
- Helpful toast notifications
- Real-time form validation feedback
- Consistent responsive design
- Fast performance with minimal re-renders
All features work together seamlessly and are demonstrated in the new `/features-demo` page. The implementation follows Rust and Leptos best practices while providing a production-ready foundation for modern web applications.
