/*
 * The UA rule behind the `hidden` attribute is `[hidden] { display: none }` at
 * zero specificity, so any class that sets `display` silently defeats it — which
 * is exactly what .app, .login-screen and .modal-root did, leaving an
 * undismissable empty modal over the login form. Toggling `hidden` from JS is the
 * app's only show/hide mechanism, so this rule has to outrank every layout class.
