/* =========================================================================
   Stempelkarte — Design-System
   Aufgebaut nach Apple-Interface-Prinzipien:
   · Response: Feedback auf pointer-down, nie erst auf Release
   · Motion: kritisch gedämpfte Springs (kein Overshoot), Bounce nur nach Impuls
   · Material: translucente Ebenen mit backdrop-filter, Tiefe statt Linien
   · Typografie: größenabhängiges Tracking, Leading invers zur Größe
   · Zurückhaltung: jedes Element verdient seinen Platz
   · Barrierefreiheit: reduced-motion / reduced-transparency / contrast
