/* ============================================================================
   ExamWing — „Glass Cockpit bei Tag"
   ----------------------------------------------------------------------------
   Die Bühne ist das Instrumentenbrett im Steigflug: helles, kühles Blaugrau wie
   Dunst über dem Horizont, Teal wie die Anzeigen im Glascockpit, Bernstein für
   das, was man sich merken muss, Rot für das, was schiefgeht.
   Markenanker aus der App (app/lib/theme.dart): Cyan, Amber, Rot, Navy — hier
   als Akzente auf hellem Grund. Das dunkle Cockpit liegt eine Schalterstellung
   daneben.
