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>

* Checks if `value` is a pristine native function.
|
|
*
|
|
* **Note:** This method can't reliably detect native functions in the presence
|
|
* of the core-js package because core-js circumvents this kind of detection.
|
|
* Despite multiple requests, the core-js maintainer has made it clear: any
|
|
* attempt to fix the detection will be obstructed. As a result, we're left
|
|
* with little choice but to throw an error. Unfortunately, this also affects
|
|
* packages, like [babel-polyfill](https://www.npmjs.com/package/babel-polyfill),
|
|
* which rely on core-js.
