/* =====================================================================
   KITTELREIF – Stylesheet
   Designidee: Klinik. Kühles Klinikweiß, Kasack-Petrol als Hauptfarbe,
   tiefes Navy wie Leitsysteme im Krankenhaus, Monitor-Grün nur auf
   dunklen Flächen (EKG, Messwerte). Untertests haben Farbcodes wie
   Stationen auf einem Wegweiser.

   Aufbau:
   1. Schriften & Farben (zentral änderbar)
   2. Grundlayout
   3. Kopfzeile, Infoleiste, Fußzeile
   4. Buttons & Formulare
   5. Bausteine: Farbcode, Monitor, Bänder
   6. Startseite
   7. Antwortbogen (überall genutzt)
   8. Üben & Simulation
   9. Guide, Vergleich, Preise, Rechtliches
