+
+## 🔧 Technical Implementation
+
+### CSS Architecture
+1. **Base styles**: `layouts.css` - Core typography and layout
+2. **Responsive design**: `responsive-accessibility.css` - Cross-device compatibility
+3. **Device-specific**: `device-specific.css` - Targeted optimizations
+4. **Component styles**: Individual component CSS files
+
+### JavaScript Enhancements
+1. **Accessibility**: `accessibility-enhancements.js` - ARIA, keyboard nav, screen readers
+2. **Device detection**: Input method detection and device classification
+3. **Focus management**: Focus trapping, restoration, and indicators
+4. **Touch handling**: Touch feedback and gesture support
+
+### Viewport Configuration
+```html
+<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=5, user-scalable=yes">
+```
+- Prevents horizontal scrolling
+- Allows zoom up to 500% (WCAG AAA)
+- Maintains usability at all zoom levels
+
