Enhance mobile experience and add zalgo text variants

Mobile improvements:
- Comprehensive responsive design for 320px-4K screens
- Touch-optimized controls with larger touch targets
- iOS zoom prevention with 16px font sizes on inputs
- Swipe-friendly interface with better spacing
- Portrait and landscape orientation support
- Enhanced accessibility with better contrast and sizes

Zalgo variants implemented:
- Full Chaos: Balanced corruption (default)
- Above Only: Marks above characters only
- Below Only: Marks below characters only
- Middle Only: Overlaying marks
- Mini Glitch: Subtle corruption
- Heavy Corruption: Maximum chaos overload

UI enhancements:
- Added corruption mode selector dropdown
- Reorganized controls into responsive groups
- Improved mobile control layouts
- Better visual hierarchy and spacing

Code quality:
- Fixed ESLint/Prettier indentation conflict
- Enhanced ZalgoGenerator with mode parameter
- Added event handlers for mode selection
- Comprehensive mobile CSS with multiple breakpoints

Documentation:
- Created comprehensive README with zalgo examples
- Documented all corruption modes with examples
- Added development and deployment instructions

The app now provides a perfect mobile experience with
diverse zalgo corruption options for creative text effects.

+## 📱 Mobile Experience
+
+GlitchCraft is designed mobile-first with:
+
+- **Touch-optimized controls** with larger touch targets
+- **Responsive layout** that adapts from 320px to 4K
+- **iOS zoom prevention** with proper font sizes
+- **Haptic feedback** for copy actions (where supported)
+- **Full-screen support** when installed as PWA
+- **Offline functionality** via service worker
+
+### Mobile Features
+- Tap output text to copy instantly
+- Swipe-friendly interface
+- Portrait and landscape support
+- Works great on tablets
+
+## 🔧 Technical Details
+
+### Architecture
+- **Pure JavaScript** - No frameworks, maximum performance
+- **Service Worker** - Full offline support with cache-first strategy
+- **Progressive Enhancement** - Works without JavaScript
+- **Accessible** - Screen reader compatible, keyboard navigation
+
+### Zalgo Algorithm
+The corruption engine uses Unicode combining diacritical marks from three categories:
+- **Above** (U+0300-U+036F): Accents and marks above characters
+- **Middle** (U+0315-U+0489): Overlaying marks  
+- **Below** (U+0316-U+0359): Marks below characters
+
+Each mode strategically applies different combinations for unique effects.
+
+### Browser Support
+- ✅ Chrome/Chromium 88+
+- ✅ Firefox 85+
+- ✅ Safari 14+
+- ✅ Edge 88+
+- ✅ Mobile browsers (iOS Safari, Chrome Mobile)
