/* Landesmark Achter'n Diek – globales Stylesheet (alle Seiten)
   Farben aus der Landesmarkfahne: Blau, Gold, Weiß.

   Aufbau
   - css/style.css    alle Seiten: Grundlagen, Layout, gemeinsame Bausteine, Hilfsklassen
   - css/start.css    nur Startseite: Video-Hero, Gau-Kacheln, Bildband, Galerie
   - css/gruppen.css  nur Gruppenseite: Filter, Gruppenliste, Karte

   Ebenen (Cascade Layers) – spätere Ebenen gewinnen unabhängig von der Spezifität:
   basis < bausteine < seiten < hilfen

   Umbrüche: 960px (Tablet), 720px (Handy), 460px (kleines Handy) – direkt am Baustein notiert.
   Keine style-Attribute: Die Content-Security-Policy blockiert sie (siehe docs/SECURITY.md). */
