Konfigurerer release-signering med keystore i ~/.android/ slik at
release-APK kan bygges og distribueres direkte.

Mozilla Public License 2.0 gir kopyleft på filnivå, men er
kompatibel med app-butikker og proprietære avhengigheter som
Google Play Services.

PWA-koden kompilerer og enhetstester passerer, men den er ikke
manuelt verifisert i nettleser ennå.

- Add scripts/fetch-shelters.sh: downloads Geonorge data, converts
UTM33N→WGS84 via PWA script, copies to both Android assets and
PWA public dirs
- Bundle pre-processed shelters.json (556 shelters) in APK assets
so the app works immediately on first launch with no network
- ShelterRepository.seedFromAsset(): seeds Room DB from bundled
JSON on first launch, marks as stale so network refresh is
attempted in the background
- MainActivity.loadData(): seeds from asset before trying network,
always attempts background refresh when data is stale
- Add version.properties (1.1.0, versionCode=2) as single source
of truth for versioning
- build.gradle.kts reads version from properties file and exposes
via BuildConfig
- Bump PWA version to 1.1.0 to match

- LocationProvider: close Flow with SecurityException when permission
is missing (instead of silently completing), log trySend failures,
handle lastLocation failure callback
- loadData(): wrap in top-level try-catch so database errors don't
leave the app in a broken loading state
- Cache retry button: show "Waiting for GPS" toast when location is
null instead of silently doing nothing
- selectShelterByData: use NaN for distance/bearing when no GPS fix
yet, so UI shows "—" instead of misleading "0 m"
- DistanceUtils.formatDistance: handle NaN gracefully
- GeoJSON parser: require valid lokalId (primary key) — reject
shelters with missing ID to prevent DB collisions

- Use repeatOnLifecycle(STARTED) for location updates so GPS stops
when Activity is paused (battery conservation)
- Pair enableMyLocation/disableMyLocation with onResume/onPause
- Add low-pass filter for accelerometer+magnetometer compass fallback
to reduce arrow jitter
- Detect missing compass sensors and show warning instead of frozen
arrow
- Monitor compass accuracy via onAccuracyChanged and indicate
degraded readings
- Show permission rationale dialog using existing i18n strings
- Guide user to Settings when location permission is permanently
denied
- Check cacheMapArea return value and show banner on failure
- Add error handling around shelter Flow and location Flow collection
- Add contentDescription to direction arrow views for screen readers
- Use safe casts for system services (as? instead of as)
- Use explicit dark theme parent (Theme.Material3.Dark.NoActionBar)
instead of DayNight with hardcoded dark colors
- Add error_no_compass and direction_arrow_description strings in
en/nb/nn

- Wrap deleteAll+insertAll in Room transaction to prevent data loss
on crash during refresh
- Add CancellationException rethrow in ShelterRepository and
MapCacheManager to preserve structured concurrency
- Close OkHttp response body on error paths (response.use{})
- Add ZIP bomb protection (10MB cap) in GeoJSON parser
- Add per-feature error handling — skip malformed records instead of
losing all shelters
- Validate coordinates within Norway's bounding box
- Enforce HTTPS-only via network_security_config (remove cleartext
allowance for tile.openstreetmap.org)
- Disable android:allowBackup to prevent DB extraction via ADB
- Strip Log.v/d/i in release builds via ProGuard to prevent location
data leakage
- Restore map position in MapCacheManager.finally block on
cancellation

Remove accidentally committed node_modules/ and dist/ directories,
and add .gitignore to prevent them from being tracked.

Vite + TypeScript PWA that mirrors the Android app's core features:
- Pre-processed shelter data (build-time UTM33N→WGS84 conversion)
- Leaflet map with shelter markers, user location, and offline tiles
- Canvas compass arrow (ported from DirectionArrowView.kt)
- IndexedDB shelter cache with 7-day staleness check
- Service worker with CacheFirst tiles and precached app shell
- i18n for en, nb, nn (ported from Android strings.xml)
- iOS/Android compass handling with low-pass filter
- Respects user map interaction (no auto-snap on pan/zoom)
- Build revision cache-breaker for reliable SW updates

Declare supported locales (en, nb, nn) via localeConfig so users can
pick the app language from system settings without changing their
device locale. Accessed via long-press → App Info → Language.

- Rework selection model so any shelter marker can be tapped to select,
not just the nearest three in the bottom sheet list
- Highlight selected shelter with a distinct amber marker icon
- Track user map interaction (pan/zoom) to prevent auto-recentering
- Add reset navigation FAB to re-fit map to user + selected shelter
- Add offline map cache prompt (OK/Skip) with warning banner and retry
- Rewrite MapCacheManager to use passive tile caching via map panning
- Respect system status bar with fitsSystemWindows

Android app (Kotlin) that locates the nearest public shelter (tilfluktsrom)
in Norway. Designed for offline-first emergency use.
Features:
- Downloads and caches all 556 Norwegian shelter locations from Geonorge
- GPS-based nearest shelter finding with distance and bearing
- OSMDroid map with offline tile caching for surroundings
- Large directional compass arrow pointing to selected shelter
- Compass sensor integration for real-time direction updates
- Shows 3 nearest shelters with distance, capacity, and address
- Toggle between map view and compass/arrow view
- Auto-caches map tiles on first launch for offline use
- Weekly background data refresh with manual force-update
- i18n: Norwegian Bokmål, Nynorsk, and English
Technical:
- EPSG:25833 (UTM33N) → WGS84 coordinate conversion
- Haversine distance and bearing calculations
- Room database for shelter persistence
- Fused Location Provider for precise GPS
- Sensor fusion (rotation vector with accel+mag fallback) for compass
