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 Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
