The system runs an X session with a minimal window manager (Openbox) that exclusively launches Firefox in full-screen Kiosk mode ( -kiosk flag). If the browser crashes, the session restarts within seconds. If a user presses Alt+F4, Ctrl+Alt+Del, or Alt+Tab—nothing happens. Those shortcuts are globally disabled.
