+## Description
+
+<!-- SECTION:DESCRIPTION:BEGIN -->
+Implement offline storage fallback so that when a browser reloads without network connectivity, it automatically loads from local IndexedDB storage and renders the last known state of the board for that user.
+
+## Implementation Summary (Completed)
+
+### Changes Made:
+1. **Board.tsx** - Updated render condition to allow rendering when offline with local data (`isOfflineWithLocalData` flag)
+2. **useAutomergeStoreV2** - Added `isNetworkOnline` parameter and offline fast path that immediately loads records from Automerge doc without waiting for network patches
+3. **useAutomergeSyncRepo** - Passes `isNetworkOnline` to `useAutomergeStoreV2`
+4. **ConnectionStatusIndicator** - Updated messaging to clarify users are viewing locally cached canvas when offline
+
+### How It Works:
+1. useAutomergeSyncRepo detects no network and loads data from IndexedDB
+2. useAutomergeStoreV2 receives handle with local data and detects offline state
+3. Offline Fast Path immediately loads records into TLDraw store
+4. Board.tsx renders with local data
+5. ConnectionStatusIndicator shows "Working Offline - Viewing locally saved canvas"
+6. When back online, Automerge automatically syncs via CRDT merge
