A video aggregator built for the house in Gzowo: one grid, one remote, and the services behind it opening full-screen in a kiosk browser instead of demanding a different device each.

Two macOS traps cost real time here and are worth writing down. Renaming the application bundle poisoned its entry in the system launcher, opening it reported success and started nothing, with an empty log and no error anywhere; only a fresh bundle identifier fixed it. And because macOS refuses to let a bundled app overwrite a file another process created under the downloads folder, the server died instantly on every start until its log moved elsewhere.
