/*
  Stylesheet des Admin-Panels „Arbeitszeugnis Studio".

  Die Design-Tokens (Farben, Radien) sind 1:1 aus dem Produkt-Design-System
  übernommen (web-arbeitszeugnis-studio/src/styles/global.css bzw. Colors.xaml),
  damit Panel, Website und Desktop-App dieselbe Design-Sprache sprechen.
  Bewusst reines, statisches CSS – kein Tailwind, kein Node-Build-Step.
  Farbwerte als "R G B"-Tripel, damit rgb(var(--token) / <alpha>) Deckkraft-
  Modifier erlaubt.
