   Formsprache wie WInf-SP, PITM, PROM und DABA: fixe Kopfleiste, Seitennavigation,
   Abschnittsbloecke, farbige Hinweiskaesten. Eigene Farbfamilie, damit die
   Lernumgebungen im Browser-Tab auseinanderzuhalten sind:

     DABA Bernstein  PROM Petrol/Lind  BINT Blau  PITM Indigo  WInf-SP Bordeaux
     Hotel-Lab Anthrazit/Kupfer

     Anthrazit #2E3238  traegt: Hero, Kopf der Lab-Seiten, Text, Links, Buttons.
                        Weisse Schrift auf Anthrazit erreicht 13,4:1.
     Kupfer    #C0662B  signalisiert: Akzentlinie, Badges, Fortschritt,
                        Kachelnummern, aktiver Prompt. Als Textfarbe auf Weiss
                        knapp (4,0:1); wo Text darauf steht, ist er weiss oder dunkel.
     Dunkelkupfer #8C4A1F ist die zweite Signalfarbe (7,4:1 auf Weiss) und
                        damit als Link- und Hoverfarbe zugelassen.
