/* ==========================================================================
   Theme-Core — variablengesteuerte Basis für die Themes in css/themes/

   Aufbau:
     core.css      (diese Datei)  Komponenten: Karte, Eingaben, Buttons, Stepper,
                                  Zusammenfassung, Validierung, MultiSelect ...
     <theme>.css                  setzt NUR --vt-* Variablen (Farben, Radien, Schatten)
                                  und ergänzt bei Bedarf Layout-Regeln (Kopf, Logo, Karte).

   Geladen wird immer core.css und danach das Theme (siehe DynamicDesignStyles).
   Danach folgt /custom.css des Vereins — das überschreibt weiterhin per !important.

   Pflichtvariablen eines Themes: --vt-accent, --vt-accent-rgb, --vt-text, --vt-text-rgb.
   Alles andere hat unten einen Default (neutral hell).
