/* =====================================================
   ESKALATOR — KI-Beschwerdegenerator

   Gestaltungsprinzip: Das Werkzeug tritt zurück, das
   Schriftstück tritt hervor. Ruhige Flächen, eine
   einzige Akzentfarbe, Serifen für alles, was nach
   Dokument aussehen soll.

   Die Eskalationsskala ist die einzige Stelle, an der
   Farbe Information trägt — deshalb bleibt sie sonst
   überall zurückhaltend.
