   Bohlhof Navigation — Single Source of Truth
   -----------------------------------------------------------------------
   Hier leben ALLE Styles fuer Header, Desktop-Navigation, Dropdowns und
   mobiles Menue. Einzelne HTML-Seiten enthalten diese Regeln nicht mehr
   inline — Aenderungen hier wirken automatisch auf alle Seiten.

   Startseite-Spezialfall:
     <header id="siteHeader" class="... over-hero">
   Darueber liegt das Hero-Video. Solange nicht gescrollt wird, ist der
   Header transparent und die Schrift hell (mit Textschatten). Sobald JS
   .header-light setzt, schaltet er auf den Frost-Look um.

   Inner-Pages: kein .over-hero — der frostige Look ist direkt aktiv.
