   DB ITSC — main.css
   Handgeschrieben, kein Framework, kein Build-Step, keine externen Requests.

   Farben stammen exakt aus der Logodatei (per Pixelanalyse ermittelt):
     Cyan       #39B1ED
     Anthrazit  #3C3C3B

   Wichtig zur Barrierefreiheit: Das Markencyan erreicht gegen Weiss nur
   2,42:1 und ist damit als Textfarbe unbrauchbar (WCAG AA verlangt 4,5:1).
   Deshalb gibt es zwei Akzent-Tokens:
     --c-accent      Flaechen, Rahmen, Icon-Hintergruende
     --c-accent-ink  Text und Links (4,95:1 auf Weiss)
   Buttons in --c-accent tragen anthrazitfarbene Schrift (4,57:1),
   NICHT weisse (2,42:1 — faellt durch).
