This site exists solely so Firebase Hosting auto-serves the auth helper endpoints for the parent Firebase project:
/__/auth/handler — OAuth redirect-flow handler/__/auth/iframe — popup-flow helper iframe/__/firebase/init.json — Firebase config consumed by the handler
Without a Hosting deployment to the project's default site, those endpoints
return 404 and signInWithRedirect / signInWithPopup
cannot complete the OAuth code-for-token exchange. App traffic does not
flow through this site — see auth.fiops.ai, portal.fiops.ai,
etc. for the actual portals.
Deployed via ./scripts/start.sh deploy:firebase-hosting:<env>
(or as Step 6 of deploy:all:<env>). See
