/* ===========================================================================
   Handbuch myContactCenter

   Farben, Schriften und Bausteine folgen ilogixx.de (Theme „ilogixx“) und
   LeadPilot: heller Grund, anthrazitfarbener Seitenkopf, Orange als Akzent.

   Zwei Regeln aus dem Theme gelten auch hier:
   - Orange ist keine Textfarbe auf hellem Grund (2,2 : 1). Für Verweise und
     Textakzente gibt es --accent-text (≈ 5 : 1).
   - Orange steht für „wartend / in Bearbeitung“, Grün für „gelöst / frei“ —
     dieselbe Lesart wie im Echtzeit-Dashboard. Grafiken halten sich daran.
