✨ Add Custom Favicon & PWA Support

SyntaxSidekick · SyntaxSidekick · commit f637c36beb56 · 2025-11-04T13:59:03.000-05:00
🎨 Custom Favicon Design:
- Created professional JavaScript-themed favicon with blue gradient background
- Features "JS" text in golden yellow with learning book icon
- Added code brackets and progress indicators for educational theme
- Multiple sizes: 32x32 main, 16x16 compact, 180x180 Apple touch icon

📱 Enhanced Mobile &amp; PWA Support:
- Added Apple touch icon (180x180) for iOS home screen
- Created manifest.json for Progressive Web App functionality
- Added theme colors for consistent mobile experience
- Enhanced meta tags for better mobile web app integration

🔧 Technical Implementation:
- SVG-based icons for scalability and crisp display
- Proper favicon hierarchy with fallbacks
- Theme color coordination (#1e40af blue)
- Apple-specific meta tags for iOS optimization
- Manifest with app metadata and icon references

🗑️ Cleanup:
- Removed default Vite.svg favicon
- Updated all favicon references in HTML
- Maintained build compatibility

The favicon now reflects the JavaScript learning theme with professional design elements including the JS logo, educational book symbol, and coding brackets, providing a cohesive brand identity across all platforms and devices."
