jubnl	0a794583d7	fix(maps): make offline tiles cover real trips (cap coherence + zoom-clamp) (#1177) ... Closes BLOCKER B5 — the offline map was blank for most real trips: - The Workbox 'map-tiles' cache held only 1000 entries while the prefetcher budgeted ~3413, so prefetched tiles were evicted on arrival. Both caps are now a coherent 12288 (~180 MB), kept in sync with cross-referencing comments. - prefetchTilesForTrip skipped a trip entirely when its all-zooms estimate exceeded the cap, so region/road-trip bboxes got no tiles. Removed the all-or-nothing guard; prefetchTiles already fills zooms low→high and stops at the budget, so large trips now cache the zooms that fit instead of nothing.	2026-06-15 07:53:12 +02:00
jubnl	b194e8317d	feat(pwa): implement real offline mode with IndexedDB sync ... Add genuine offline read/write capability for trips: - Dexie IndexedDB schema (trips, places, packing, todo, budget, reservations, files, mutationQueue, syncMeta, blobCache) - Repo layer for all domains: offline reads from Dexie, writes optimistically to Dexie and enqueue mutations for later replay - Mutation queue with UUID idempotency keys (X-Idempotency-Key), FIFO flush, temp-ID reconciliation on 2xx, fail-and-continue on 4xx - Trip sync manager: caches all trips with end_date >= today or null, auto-evicts 7d after end_date, fetches bundle endpoint in one request - Map tile prefetcher: bbox from place coords, zooms 10-16, 50MB cap, warms SW cache via fetch - Sync triggers: network online → flush + syncAll; WS reconnect → flush only (rate-limiter safe); visibilitychange/30s → flush only - WS remoteEventHandler writes through to Dexie on every event - Server idempotency middleware + idempotency_keys table (migration 100, 24h TTL nightly cleanup) - GET /api/trips/:id/bundle endpoint for efficient single-request sync - OfflineBanner component: amber (offline) / blue (syncing) / hidden - OfflineTab in Settings: cached trip list, re-sync and clear actions - usePendingMutations hook for per-item pending indicators Closes #505 #541	2026-04-14 23:04:25 +02:00
