- 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.
Real screenshots from the shared demo account (neutral, repo-safe — no personal
data), captured via headless Edge + CDP with the demo session cookie injected.
Fills the feed (hero) and playlists preview slots on the landing page; the channels
slot stays a graceful labelled placeholder (the demo has no subscriptions).
