   CALENBERG — REFERENZEN

   Stylesheet für die Projekt-Übersicht (/projekte/) und die neuen
   Referenz-Detailseiten. Lädt NACH projekt.css — Tokens, Nav, Footer

   Struktur orientiert sich am Referenz-Aufbau (Übersicht mit
   Featured-Karte + 2-Spalten-Raster, Detailseite mit Fakten,
   Aufgabe, Ansatz, Formaten, Zahlen) — Farben, Rundungen und
   Typo sind Calenberg.
