   DITKO — Neubau 15.09.2026
   Eine Seite, ein Faden: oben der Scroll-Film (Kamerafahrt vom Büro auf den
   Bildschirm), darunter die Stationen an einer Linie in der Mitte, die beim
   Lesen mitwächst. Optik: viel Weiß, große enge Überschriften, wenige Farben.
   Regel: Bewegung nur mit html.js und nur, wenn der Besucher sie nicht
   abgeschaltet hat.
