/* Prüfung und Zertifikat im Design 2027 (Teilnehmerseiten, Root-HTML).
   Auszug aus src/styles/site-2027.css und website-entwurf-2027/seiten/seiten.css:
   Farben, Schrift, Raster, schlanke Kopfzeile, Foto-Hero, Karte, schmale Fusszeile.
   Die Seiten bleiben eigenständige HTML-Dateien (Live-Skripte unverändert), darum
   eine eigene Datei statt des Astro-Bundles. Seitenspezifisches steht in der Seite. */
