   Rufo — „Cockpit bei Nacht"
   ----------------------------------------------------------------------------
   Die Bühne ist das nächtliche Instrumentenbrett: tiefes Blauschwarz, Bernstein
   wie Panelbeleuchtung, Funksprüche in Schreibmaschinenschrift wie auf dem
   Streifen. Die App-Screens leuchten darin wie Instrumente.
   Markenanker aus der App (lib/config/theme.dart): Terracotta, Sol, Himmel,
   Sand — hier als Akzente auf dunklem Grund statt als Grundfläche.
