/* =========================================================================
   fk-django-core - Grunddesign aller Anwendungen der Plattform.

   Aufbau:
     1. Tokens          Farben, Abstaende, Radien, Schrift
     2. Grundlagen      Reset, Typografie, Fokus
     3. Shell           Sidebar, Kopfleiste, Inhalt, Responsive
     4. Komponenten     Buttons, Formulare, Tabellen, Karten, ...
     5. Anmeldeseiten
     6. Hilfsklassen

   Branding greift ausschliesslich ueber --fk-primary und --fk-accent ein.
   Alles andere bleibt ueber alle Anwendungen gleich.
