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)
