   design-d.css – Gestaltung „Register“ (Entwurf D)
   Stand: 27.09.2026

   Überlagert styles.css und patches.css und wird auf jeder Seite als
   letztes Stylesheet geladen. Die Farben der Bestandskomponenten laufen
   über die vorhandenen Design-Tokens (--bg, --text, --accent …); hier
   werden die Tokens neu belegt und die sichtbaren Bausteine an das neue
   Erscheinungsbild angepasst.

   Registerfarben: Jedes der vier Themenfelder hat eine Farbe
     A Grundlagen Datenschutzrecht   (blau)
     B Hochschul- & Verwaltungsrecht (grün)
     C Drittland & KI                (bernstein)
     D Vorfälle & IT-Governance      (rosé)
   Seiten setzen data-register="a|b|c|d" (z. B. auf <main>); alle
   Bausteine darin verwenden dann --g (Fläche) und --g-ink (Schrift).

   Schriften (selbst gehostet, SIL Open Font License 1.1):
     Bricolage Grotesque – Überschriften
     Atkinson Hyperlegible Next – Fließtext und Bedienelemente
     IBM Plex Sans/Mono – bleiben für Diagramme und Code
   CSP-konform: keine Inline-Styles, keine externen Quellen.
