/* --------------------------------------------------------------------------
   Kontrast-Hinweis
   Das Brand Book sieht #838BA0 für Labels und #949493 für Captions vor.
   Beide erreichen auf #FBFCFD nicht die 4,5:1 der WCAG 2.1 AA für Fließtext.
   Für Text werden daher die minimal abgedunkelten Werte --c-accent (#6A7288,
   4,67:1) und --c-body (#6A6A69, 5,74:1) verwendet; als Linie/Fläche bleibt
   #838BA0 exakt erhalten (--c-accent-rule). Der optische Eindruck ist
   praktisch unverändert, die Seite erfüllt damit WCAG 2.1 AA.
