/* ============================
   KitchenCloud – Theme: Auth
   ============================
   Styling für Login & Registrierung (Views/AuthGui/*).
   Baut auf den Farbvariablen aus kc-theme.css auf (--kc-primary, --kc-bg, ...),
   diese Datei wird deshalb IMMER NACH kc-theme.css eingebunden (siehe
   _Layout.cshtml -> Section "Styles").

   Aufbau:
   1) Seiten-Hintergrund (Hero-Panel + weiche Farbflächen)
   2) Zwei-Spalten-Shell (Bild-Panel + Formular-Karte)
   3) Login/Registrieren-Tabs
   4) Eingabefelder mit Floating-Label
   5) Buttons
   6) Fehlermeldung
   7) Einblend-Animationen
   8) Responsive (Mobile)
   ============================ */

/* ----------------------------

   Lime-Hintergrund des Body abhebt. Zwei weiche, verschwommene Farbflecken
   (::before/::after) sorgen für Tiefe, ohne dass echte Bilder geladen werden. */
