-// Open CAD Studio web app service worker: offline app-shell caching.
-//
-// Trunk copies this file to dist/app/sw.js (copy-file link in web-app.html),
-// so it is served at /app/sw.js and its scope is /app/ — the whole app. The
-// page registers it with a relative URL; see the inline script in
-// web-app.html.
-//
-// Caching strategy
-//   - Navigations (any path under /app/, deep links included): network-first.
-//     A successful response is cached under the canonical shell URL (the
-//     scope root) and returned, so updates land on the next visit; offline
-//     the cached shell is served instead, which also serves as the fallback
-//     for deep-linked paths.
-//   - Other same-origin GET requests (wasm, js, workers, fonts, JSON):
-//     cache-first with a background revalidate. Trunk content-hashes the
-//     heavy assets (OpenCADStudio-<hash>[_bg].{js,wasm}), so a cached copy
-//     can never be stale and revalidation is effectively free; non-hashed
-//     files (fonts/*.ttf, *.json, ocs-*.js) are silently refreshed in the
-//     background. Everything the app loads is captured during the first
-//     online visit, after which the ~55 MB bundle is served from the cache
-//     instead of re-downloaded on every visit.
-//   - Non-GET and cross-origin requests: passthrough (never intercepted).
-//
-// Versioning
-//   CACHE_VERSION below is a placeholder ("v1") so this file works verbatim
-//   under `trunk serve`. The Pages workflow stamps it with a hash of the
-//   finished bundle after every build, so each deploy ships a fresh cache
-//   name and the activate step below deletes the previous deploy's cache.
-//
-// Update flow
-//   A changed sw.js installs a new worker, but this code deliberately never
-//   calls skipWaiting() and never reloads the page: the browser keeps the
-//   new worker in the "waiting" state until every tab running the old
-//   version has closed, so an in-progress editing session is never disrupted
-//   mid-session. The new worker (and its new cache) takes over on the first
-//   visit after that. Nothing is shown to the user — the browser chrome
-//   already handles the "update available" UX.
