/launch the backend 302s to your operator's game_frontend_base_url with ?game=…¤cy=… appended, and this page auto-mounts the game. Set that column to where this page is served — e.g. http://localhost:8912/ (this folder as web root). If it's left as …/launch-landing, the bundled launch-landing/ forwarder handles it when this folder is the web root. The page must be served from an origin the backend's session cookie + CORS allow.
