   KI-Adventskalender · Stylesheet
   Konzept "Winterlicht": ruhige Papierflächen, eine klare Markenfarbe,
   ein warmes Licht als einziger Advents-Akzent. Details in docs/DESIGN.md.

   Aufbau
   1. Tokens: Grundwerte (themeunabhängig)
   2. Theme "standard" hell + dunkel (weitere Themes in css/themes/*.css)
   3. Basis, Typografie, Hilfsklassen
   4. Komponenten (Buttons, Formulare, Topbar, Login, Dashboard,
      Türchen, Tagesinhalte, Abschlusstest, Zertifikat, Rückmeldungen)
   5. Bewegung, Druck
