  // v1.4.33 IW2 — bfcache hygiene. `Permissions-Policy: unload=()`
  // tells the browser the page does not need the `unload` event,
  // which Chromium uses as a hint to admit the page to the
  // back/forward cache on navigation away. Pair with the absence of
  // any `beforeunload` / `unload` listener in our own code so the
  // bfcache restore path stays clear. The other CSP-style security
  // headers already live on the response via the standalone runtime;
  // we add only the bfcache hint here.
  //
  // v1.4.34 IW-A — second rule layers the bfcache-friendly
  // `Cache-Control` directive onto every authenticated HTML page
  // response (the source negative-lookahead excludes `/api/*` and
  // `/_next/*` so static assets keep their immutable caching and API
  // routes keep their explicit headers). The framework default for
  // pages that read cookies is `no-store, must-revalidate`, which
  // Chromium counts as a hard bfcache breaker. `private, max-age=0,
  // must-revalidate` keeps shared caches out (proxies, CDNs cannot
  // store personal data), still forces revalidation on every
  // navigation so session swaps detect on the wire, and is
  // bfcache-eligible — back/forward navigation restores the page
  // from memory instead of paying a full reload. See
  // `src/lib/http/cache-headers.ts` for the typed constant reused by
  // route handlers that opt into the same posture.
