   HVAC Solution — Relaunch-Standard 27.09.2026
   Neue Bausteine: Seitenbühnen, Gewerke-Strecke, Anfrage-Bühne,
   Zickzack mit großen Bildern, Scroll-Wandel (Rohbau -> fertig),
   Pflicht-Bühne, Ablauf-Bühne, Prüfpflichten-Check, Luftbild.
   Baut auf style.css auf (Tokens, Buttons, Typo).
   Bilder liegen nie hinter Einblend-Effekten: alles ist ohne JS
   sichtbar, Bewegung kommt nur scrollgesteuert dazu.
