  - Active windows count (scales with pulse)
  - Alerts count
  - System online percentage
- **Glow Effect**: Large blurred circle overlay for depth
- **Interactive Stats**: Each stat has hover scale effect

### Window Management
- **Swipe Gestures**:
  - Drag right: Close current app
  - Drag left: Switch to next app
  - Elastic drag constraints
  - Opacity fade during drag
- **Spring Animations**: Type 'spring' with stiffness 300, damping 30
- **Header Gradient**: From slate-900 to slate-800 with blur
- **Multi-App Badge**: Shows number of open windows with spring animation
- **Icon Wiggle**: Active window icon rotates gently

### Bottom Navigation
- **Enhanced Buttons**:
  - 4 main tabs: Home, Alerts, Settings, Account
  - Gradient background on active tab
  - Pulsing glow effect on active
  - Icon float animation (y-axis bounce)
  - Badge pulse on notifications
- **Haptic Feedback**: Medium impact on every tap
- **Stagger Entry**: Buttons fade in with 50ms delays
- **Active State**: Radial gradient pulse behind active icon

## 📳 Haptic Feedback Integration

### Implementation
```typescript
const { impact, notification } = useHaptics();

// Light haptics for subtle interactions
impact('light') // Scrolling, selection changes

// Medium haptics for standard interactions
impact('medium') // Button taps, tab switches

// Heavy haptics for important actions
impact('heavy') // Logout, delete actions

// Success notifications
notification('success') // App launched, clearance switched

// Warning/Error notifications
notification('warning') // Form validation
notification('error') // Action failed
```

### Haptic Mapping
- **App Icon Tap**: Medium impact + Success notification
- **Bottom Nav Tap**: Medium impact
- **Close Window**: Medium impact
- **Swipe to Close**: Medium impact
- **Panel Open/Close**: Light impact
- **Clearance Switch**: Medium impact + Success notification
- **Logout**: Heavy impact + Success notification
- **Widget Tap**: Light impact
- **Notification Card Tap**: Light impact

## 🎭 Animation Details

### Spring Physics
```typescript
transition={{ type: 'spring', stiffness: 300, damping: 30 }}
```
- Used for all major transitions
- Creates natural, bouncy feel
- Enhances perceived responsiveness

### Pulse Animations
```typescript
animate={{ scale: [1, 1.1, 1] }}
transition={{ duration: 2, repeat: Infinity }}
```
- Active tabs pulse continuously
- Notification badges pulse
- Status badges pulse

### Gradient Animations
```typescript
animate={{ opacity: [0.2, 0.4, 0.2] }}
transition={{ duration: 2, repeat: Infinity }}
```
- Background glows fade in/out
- Creates dynamic, alive interface

### Stagger Effects
```typescript
initial={{ opacity: 0, y: 20 }}
animate={{ opacity: 1, y: 0 }}
transition={{ delay: idx * 0.03 }}
```
- App icons appear sequentially
- Bottom nav buttons cascade in
- Creates polished loading experience

## 📱 Native Features

### Status Bar
- **Dark Theme**: Matches app aesthetic
- **Background Color**: `#0a0a0a` (dark slate)
- **Auto-configured**: Runs on component mount

### Splash Screen
- **Fade Duration**: 300ms
- **Auto-hide**: After app loads
- **Smooth transition**: To main interface

### Keyboard Management
- **Event Listeners**: Tracks show/hide/resize
- **State Tracking**: `keyboardVisible` boolean
- **Auto-hide Function**: `hideKeyboard()` method
- **UI Adaptation**: Can adjust layout when keyboard shows

## 🎯 Swipe Gestures

### Pull-to-Dismiss Panels
- **Notifications Panel**: Swipe down > 200px to close
- **Account Panel**: Swipe down > 200px to close
- **Visual Feedback**: Swipe handle at top
- **Animated Handle**: Pulses to indicate draggability
- **Haptic Response**: Medium impact on successful dismiss

### App Switching
- **Horizontal Swipe**: Drag left/right on app window
- **Threshold**: 100px offset triggers action
- **Elastic Drag**: Constrained but springy
- **Opacity Fade**: Window fades during drag
- **Spring Back**: Returns to center if threshold not met

## 🎨 Glassmorphism Effects

### Implementation Pattern
```typescript
className="backdrop-blur-2xl bg-gradient-to-b from-slate-900/95 via-slate-900/90 to-slate-950"
```

### Applied To:
- Status bar
- Bottom navigation
- Modal panels (Notifications, Account)
- System widget cards
- Notification cards
- Button active states

### Visual Result:
- Translucent layers
- Depth perception
- Premium aesthetic
- Reads well over any background

## 🔄 Loading States

### Empty States
- **Animated Icons**: Rotate and scale
- **Friendly Messages**: "All caught up!", "No notifications"
- **Consistent Design**: Follows app theme
- **Centered Layout**: Vertically and horizontally

### Skeleton Loaders
- Can be added for async data
- Use Framer Motion's `layoutId` for smooth transitions
- Maintain layout during loading

## 📊 Performance Considerations

### Optimization Strategies
1. **Transform-based Animations**: Use `transform` (scale, translate) for 60fps
2. **Backdrop Filter**: Limited usage to critical areas
3. **Gradient Caching**: CSS gradients are GPU-accelerated
4. **Motion Reduce**: Can add `useReducedMotion` hook for accessibility
5. **Lazy Loading**: Apps can be dynamically imported
6. **Image Optimization**: Icons are SVG for crisp scaling

### Current Bundle Size
- Client JS: 1.62 MB (435 KB gzipped)
- CSS: 178 KB (24.8 KB gzipped)
- APK: ~10 MB

## 🚀 Next Steps

### Potential Enhancements
1. **Pull-to-Refresh**: On app launcher (refresh app list)
2. **Long-Press Menus**: Context menus on app icons
3. **Gesture Tutorial**: First-time user onboarding
4. **Dark/Light Theme**: Toggle in settings
5. **Haptic Patterns**: Custom vibration sequences
6. **3D Touch**: Peek and pop on supported devices
7. **Biometric Auth**: Fingerprint/Face ID
8. **Camera Integration**: For profile pictures
9. **Share Sheet**: Export data to other apps
10. **Push Notifications**: Real-time alerts

### Advanced Animations
1. **Parallax Scrolling**: App launcher background
2. **Physics-based Springs**: Even more natural motion
3. **Morphing Shapes**: Icon transformations
4. **Particle Effects**: On special actions
5. **Lottie Animations**: Complex animated illustrations
