Summary

I've successfully implemented a comprehensive logo system for your Rustelo project. Here's what has been accomplished:

### ✅ **Logo System Implementation**

1. **Created Logo Components** (`template/client/src/components/Logo.rs`)
   - `Logo` - Basic logo component with theme detection
   - `LogoLink` - Clickable logo with navigation
   - `BrandHeader` - Complete brand header with logo and text
   - `NavbarLogo` - Optimized navbar logo component

2. **Updated Navigation** 
   - Replaced "Material Tailwind" placeholder with proper Rustelo logo
   - Added theme-aware logo switching

3. **Public Asset Management**
   - Copied all logo variants to `public/logos/` directory
   - Made logos web-accessible

### ✅ **Documentation Integration**

1. **README.md** - Added centered logo header
2. **mdBook Documentation** - Added logo to introduction page
3. **mdBook Configuration** - Added favicon and logo settings
4. **Custom CSS** - Added logo styling and responsive design
5. **Logo Usage Guide** - Comprehensive documentation for developers

### ✅ **Use Cases Covered**

1. **Main MD Pages** - Logo implemented in README with uppercase "RUSTELO"
2. **Book Documentation** - Logo integrated into mdBook with proper styling
3. **Cargo Doc Integration** - Added metadata for cargo doc logo support

### ✅ **Theme Support**

- Automatic light/dark theme detection
- Separate logo variants for different themes
- Responsive design for mobile devices

### ✅ **Developer Resources**

- Complete logo usage guide
- Copy-paste templates for markdown files
- API reference for all logo components
- Best practices and troubleshooting guide

The logo system is now fully integrated and ready to use. The components will automatically select the appropriate logo variant based on the current theme, and you have comprehensive documentation to guide future usage.

To start using the system, simply import the components in your Rust code or use the provided markdown templates for documentation pages.
