-### Service Worker (`public/sw.js`)
-- **Strategy**: Network-First. Attempts to fetch from network, falls back to cache if offline.
-- **Cache Bypassing**: Explicitly bypasses cache for:
-    - `*/auth/*`
-    - `*/api/*`
-    - `*.supabase.co/*`
-- **Asset Caching**: Caches static assets (`manifest.json`, icons) during installation.
+### Service Worker (`public/sw.js`) - "Ironclad" Strategy
+The Service Worker implements an aggressive offline reliability strategy:
+
+- **Pre-Caching**: The landing page (`/`) and core static assets are cached during installation.
+- **Fail-Fast Navigation**: Navigation requests have a 3-second timeout to prevent UI hangs during network transitions.
+- **Root App Shell Fallback**: If a URL is not found in the cache while offline, the SW serves the Root (`/`). This allows Next.js to bootstrap and handle the routing client-side using local Dexie data.
+- **RSC Data Resiliency**: Requests to `/_next/data/` return an empty JSON object if they fail, preventing "Application Error" screens.
+- **Stale-While-Revalidate**: Applied to static assets to ensure immediate UI response.

 - `src/lib/db.ts`: Database definition and TypeScript interfaces.
 - `src/hooks/useBottleData.ts`: Example of the SWR pattern implementation.
 - `src/components/UploadQueue.tsx`: The "Sync Engine" UI and logic coordinator.
+- `src/components/CameraCapture.tsx`: Integrated scanning feature.
+- `src/components/TastingNoteForm.tsx`: Integrated tasting note feature.
 - `src/components/PWARegistration.tsx`: Client-side Service Worker registration handler.
 
 ## ⚠️ Edge Case Handling
 - **Partial Sync**: If a scan succeeds but a tasting fails, the tasting remains in the queue with the now-valid `bottle_id`.
-- **Duplicate Scans**: The system relies on the user not submitting the same scan multiple times while offline (UI prevents multiple clicks).
 - **Stale Cache**: Caches are overwritten on every successful online fetch to ensure eventual consistency.
