/* =========================================================
   Berufsbildung IDS – gemeinsames Design (Version 2)
   Angelehnt an stadt.sg.ch: weisse Kopfzeile, Logo «//st.gallen»,
   Arial, Rot #E00025, Beige #D8D5C5, ruhige Flächen.

   Aufbau:
     1. Variablen (Farben, Abstände, Schrift) + Dunkelmodus
     2. Grundlagen
     3. Kopfzeile, Fusszeile
     4. Seitenkopf, Begrüssung, Kacheln (Startseite)
     5. Bausteine: Knöpfe, Formulare, Karten, Tabellen,
        Meldungen, Marken, Reiter, Kennzahlen, Dialoge, Leerzustand
   Farben nur über die Variablen ändern. Regeln: keine roten
   Deko-Striche/Balken, «//» nur im Logo.
