/**
 * Service worker. Bundled to `dist/sw.js` by `vite.sw.config.ts` (see the
 * `build:sw` script) and registered from `src/main.tsx`.
 *
 * Layers, in order:
 *  1. Push + notifications + skip-waiting (the SDK push helpers).
 *  2. Background sync — failed API mutations are queued and replayed online.
 *  3. Runtime caching: API GETs (network-first) + media (cache-first with
 *     Range support, so audio/video seeking works offline).
 *  4. Precache of the app shell so the app launches offline. Reads the
 *     `precache-manifest.json` emitted by `tempestPwaManifest()` in
 *     `vite.config.ts`.
 *
 * `installRuntimeCache` is registered BEFORE `installPrecache` so its specific
 * routes win over the precache catch-all.
