H8: prefetched tiles and file blobs could be evicted under storage pressure
(worsened by opaque tile responses inflating the quota ~7MB each), blanking the
offline map right when a traveler needs it. Request persistent storage at app
init so the browser exempts our caches from eviction. We deliberately keep tile
requests no-cors (a cors switch would break self-hosted/custom tile providers
without CORS headers), so persistence is the safe mitigation rather than
de-opaquing responses.
H9: Mapbox GL users had no offline map at all — no runtimeCaching matched the
Mapbox hosts. Add a StaleWhileRevalidate rule for api.mapbox.com /
*.tiles.mapbox.com so visited areas are available offline (best-effort; full
pre-download still requires the Leaflet renderer, now documented).
- new sync/persistentStorage.ts requestPersistentStorage(), called from main.tsx
- vite.config: mapbox-tiles SW cache rule
- MapViewAuto / tilePrefetcher comments document the offline-maps policy
- tests for the persist helper (granted / already-persisted / absent / rejects)
- Mapbox GL provider alongside Leaflet for trip and journey maps (opt-in in
settings with token, style presets incl. 3D on satellite, quality mode,
experimental badge).
- GPS "blue dot" with heading cone on mobile; three-state FAB (off / show /
follow), geodesic accuracy circle, desktop-hidden since browser IP geo is
too coarse for navigation.
- Marker drift fix: outer wrap no longer carries inline position/transform,
so mapbox's translate keeps the pin pinned at every zoom and pitch.
- Journey map popup (mapbox-gl): Apple-Maps-style tooltip on marker
highlight/click showing entry title + location / date subline.
- Journey feed reorder: up/down controls to the left of each entry reorder
sort_order within a day. Server endpoint, optimistic store update, rollback
on failure.
- Journey entry editor: desktop modal now centers over the feed column only,
backdrop still blurs the whole page (map included).
- Scroll-sync guard on journey: marker click locks the sync so smooth-scroll
can't steer the highlight to a neighbouring entry mid-animation.
- Misc: map top-padding aligned with hero, live/synced badges replaced by a
compact back-button in the hero, skeleton entries no longer pollute the
journey map, journey detail no longer shows map on mobile path when
combined view is active.
