## Technical Architecture
### Caching Strategy
```
Static Assets (Cache-First):
├── HTML, CSS, JavaScript
├── Fonts and icons
└── Instant load from cache
API Data (Network-First):
├── Watch data
├── Statistics
├── Collections
└── Fresh data when online, cache when offline
Images (Cache-First):
├── Watch images
├── Icons
└── Fast display from cache
```
### Data Flow
```
Online Mode:
User Request → Network → Cache → IndexedDB → Update UI
Offline Mode:
User Request → Cache → IndexedDB → Update UI
Sync Mode:
Pending Actions → Background Sync → Server → Update Cache
```
### Service Worker Lifecycle
```
Install → Cache Static Assets
Activate → Clean Old Caches
Fetch → Serve from Cache/Network
Sync → Upload Pending Actions
Push → Show Notifications
```
