 * The immersive signed-out screens
 *
 * resources/views/filament/auth/immersive.blade.php, chosen per audience in the
 * sign-in screen settings. Registered on both panels because both can use it;
 * every rule is scoped inside `.ai-shell`, so nothing here reaches a screen that
 * did not ask for it — and the classic screens, which are the way back, are
 * untouched.
 *
 * The scene is deep in both themes. It is a room with the lights down and the
 * brand's colour moving in it, and a light version of that is a pale gradient —
 * exactly the kind of flat backdrop this replaces. The form column follows the
 * theme like the rest of the panel.
