Offline-Karten Follow-ups: Staging-Default AN, Karten-Download-Button, Glyph-Persistenz
- by_offline_tiles Default AN auf staging.banyaro.app (localStorage/?tilesoffline=1/0 uebersteuert) - Speed-Dial 'Karte offline speichern': GL -> MapOffline.downloadAround(Kartenmitte, 5km), Leaflet -> alter Raster-Prefetch (_cacheTiles war seit FAB-Redesign verwaist) - Glyphs in IndexedDB (Key-Praefix f/) + byt://f/-Protokoll: ueberlebt App-Updates - OSM-Raster-Prefetch im Offline-Tiles-Modus uebersprungen (GL nutzt das Raster nicht) - Button-Sichtbarkeit gated: GL ohne Offline-Flag (= Production) zeigt ihn nicht
