/* ============================================================
   Omnia – Auth-Seiten (App-Login, Control-Plane-Login, Einrichtung)
   Referenz: .claude/Login Redesign/design_handoff_login_unification/README.md

   Bewusst standalone: login.php laedt nur variables.css + diese Datei (kein App-Bundle),
   admin.php laedt zusaetzlich admin-variables.css + admin.css. Damit beide Seiten identisch
   aussehen, bringt diese Datei die Tokens selbst mit (gleiche Werte wie admin-variables.css)
   und definiert Felder, Buttons und Meldungen unter .auth-page - dadurch gewinnt sie gegen
   die kompakteren Admin-Basisregeln, ohne sie ausserhalb der Auth-Seiten zu veraendern.
