- Build the Google OAuth client lazily from sysconfig (DB override, env fallback) and re-register
when the credentials change, so the install wizard / admin can set them without a restart.
- New 'google' config group (google_client_id/secret, encrypted) on the Configuration page; the
token-refresh reads the creds the same way.
- Public GET /auth/config exposes google_enabled; the login page hides 'Continue with Google'
when Google OAuth isn't configured (email+password still works).
- Serve real files at the SPA root (e.g. /welcome/*.png, favicon) from the built app — the
landing screenshots were only ever shown by the Vite dev server, never in production.
- Add the Channel-manager screenshot; the two secondary previews are smaller thumbnails that
open in a custom full-size lightbox (fit-to-viewport, Esc/backdrop/✕ to close).
- Drop a suspended/deleted user to the login page on the next 401 (and poll the session only
while signed in, so the public login page no longer flickers); 'suspended' and 'account
deleted' confirmation banners; strip redirect query params for a clean address bar.
Replace the old Google-only login card with a public landing page (Welcome.tsx):
hero + auth card (email+password Sign in / Create account / Forgot password,
Continue with Google, explicit Try-the-demo) over a feature pitch (6 pain->solution
cards) and demo-account screenshot slots (graceful placeholder until the images are
dropped into frontend/public/welcome/). Auth forms wire to the 5a endpoints; errors
show inline via a new req() quiet flag (no global modal for a wrong password).
Handles ?verify, ?reset (set-new-password form), ?access banners. EN/HU/DE.
Verified end-to-end on a fresh load: render, register->approve->password-login.
