  Phase ER-8 app-host sitemap (11 Jul 2026).

  Served on `app.reference-ninja.com` via a Firebase Hosting rewrite
  (`/sitemap.xml` -> `/sitemap-empty.xml`) configured on the app
  target in `firebase.json`. An empty urlset is a valid sitemap that
  declares zero indexable URLs — safer than returning 404 (crawlers
  get a normal 200 with an authoritative "nothing to index" signal).
  The public host at `reference-ninja.com` continues to serve the
  real sitemap.xml with only the public marketing/legal URLs.
