Swap the two "Free and open source" / "Community driven" text cards on the start page for the intro-video thumbnail with a play badge; clicking it opens the video in the system browser (new Message::OpenUrl → sys::open_url). The bundled thumbnail Handle is built once via OnceLock — Handle::from_bytes mints a fresh unique id per call, so rebuilding it per view re-decoded and re-uploaded the JPEG every frame and the image only appeared after a long delay.
