web/index.html loads the Firebase compat SDK and defines window.kcGetPushToken() — inits Firebase from window.KC_FIREBASE, asks for notification permission, registers the service worker and returns an FCM token (or null if not configured / denied). web/firebase-messaging-sw.js shows background notifications. browser_web.dart exposes getPushToken() over that JS function (stub returns null off-web). After every successful login AppState fires _registerForPush() -> POST /api/push/register, best-effort. Config placeholders carry the known values (projectId konfi-castle-app, messagingSenderId 307226979593); apiKey / appId / vapidKey still say REPLACE_ME, so push stays inert until they're filled in — the app runs either way. flutter analyze/test/build web green.
