/* =========================================================
   Dachtechnik Menke — Fassung 2, komplett neu aufgebaut

   Fassung 1 war strukturell zu nah am Bußmann-Entwurf und der
   Hero war kaputt (Elemente hingen aus dem Rahmen).
   Jetzt: mittiger Einstieg, das Vorher/Nachher trägt die Seite,
   Leistungen als nummerierte Liste statt Kachelraster.
   Keine animierten Bilder — der Vergleich wird gezogen, nicht abgespielt.
