/* ==========================================================================
   wir machen deine heizung. — Redesign Startseite (Oktober 2026)
   redesign.css · identisch im Claude-Design-Canvas und in der Umsetzung

   Aufbau
   - Die gesamte Seite steckt in <div class="site">. .site ist ein
     Container-Query-Container: alle Breakpoints sind @container-Regeln.
   - Motion ist Progressive Enhancement: Grundzustand = Endzustand.
     Zeitbasierte und scroll-gekoppelte Animationen laufen nur bei
     prefers-reduced-motion: no-preference (und Scroll-Effekte nur dort,
     wo animation-timeline unterstützt wird).
