Phase 4 establishes the core application structure with SvelteKit routing,
data loading, error handling, and state management.
## Routing & Data Loading
- Created root layout load function (+layout.ts) with app version and feature flags
- Implemented comprehensive error boundary (+error.svelte) with status-based messages
- Added page loaders for homepage, matches, players, and about routes
- Homepage loader fetches featured matches via API with error fallback
- Matches loader supports URL query parameters (map, player_id, limit)
## State Management (Svelte Stores)
- preferences.ts: User settings with localStorage persistence
* Theme selection (cs2dark, cs2light, auto)
* Favorite players tracking
* Advanced stats toggle, date format preferences
- search.ts: Search state with recent searches (localStorage)
- toast.ts: Toast notification system with auto-dismiss
* Success, error, warning, info types
* Configurable duration and dismissibility
## UI Components
- Toast.svelte: Individual notification with Lucide icons
- ToastContainer.svelte: Fixed top-right toast display
- Integrated ToastContainer into root layout
## Fixes
- Fixed Svelte 5 deprecation warnings (removed <svelte:component> in runes mode)
- Updated homepage to use PageData from loader
- Added proper type safety across all load functions
## Testing
- Type check: 0 errors, 0 warnings
- Production build: Successful
- All Phase 4 core objectives completed
