   Gestaltungsidee: "Aktenordner" – ein ruhiges, lineares Ledger-Layout statt
   Diagonalschnitten und Icon-Kacheln. Bilder und Primär-Buttons tragen einen
   versetzten Rahmen ("Stempel"), der an einen Eingangsstempel auf Unterlagen
   erinnert. Alles andere bleibt bewusst zurückhaltend: keine Schatten-Karten,
   keine Farbverläufe, keine Großbuchstaben-Labels.
