The Admin Panel is hardened: Admin Access is proved against a single-use challenge, the PIN and lockout are held by the device, sessions expire, and requests are refused unless they name an address this Kiosk answers at.
The Kiosk now shows its version and build number, on the device and in the Admin Panel.
Keep Screen On works, and the Kiosk lists the addresses it can really be reached at.
Now targets Android 16; back still cannot leave the Kiosk there.
