/*
  Modul B intensiv - Praxiskurs Sprach- und Literacy-Förderung im Vorkurs
  Gemeinsames Stylesheet für alle Seiten.

  Farbtoken übernommen aus dem bestehenden VKD-Webprototyp (Kurs 2):
  --gruen (Kita-Zone) für Praxiskarten, --gelb als Akzent für Kompaktboxen.
  --tuerkis ist die für diese Website neu gewählte Leitfarbe (Modul B hat
  laut Projektstand noch keine offizielle Kurs-1-Farbe im Corporate Design -
  siehe offene-punkte.md). Türkis stand im Prototyp bereits für "Tandem"
  (Kooperation Kita/Grundschule) und passt inhaltlich, da Modul B beide
  Berufsgruppen anspricht, die den Vorkurs gemeinsam tragen.
