/**
 * The web app is not copied into the repo — it is read out of public_html at
 * build time, so the browser version and the app version cannot drift.
 *
 * sw.js is left behind on purpose: it is cache-first, and a service-worker cache
 * outlives an app upgrade, so it would go on serving the old index.html with no
 * way to clear it. Without the file the registration fails into its own .catch,
 * and the APK is the cache instead.
