/*
 * Login (wp-login.php) incl. the next-events-2fa challenge/setup views.
 *
 * Uses the shared design tokens (pt-tokens.css is loaded as dependency) and
 * the same theme logic as the app: stored choice via pt_theme_bootstrap_script(),
 * otherwise the OS preference. Branding (logo variants, poster) comes from
 * Systemeinstellungen → Design and is injected by Theme::enqueue_login_assets()
 * as custom properties — never hardcoded here.
 *
 * !important is only used where WordPress core login styles would win.
