   chrome.css — KANONISCHER Header (.nav) + Footer (.footer) für die GESAMTE Site.
   Einzige Quelle der Wahrheit (M5/M6-Header-Konsolidierung, Option B, 2026-06-24).
   Referenz-Optik: /verkaufen/ (nav.nav, 72px, Emblem + Hanken-Wortmarke, Burger,
   Bordeaux-Pill-CTA). Wird von ALLEN Oberflächen geladen (statische Seiten, v3-
   Startseite, immobilien-SPA, einwertung, suchauftraege; React-rechner rendert
   dieselbe Markup-Struktur).

   Modifier `.nav--hero`: transparenter Header über einem Vollbild-Hero
   (Startseite, immobilien-Liste). Wird via JS (chrome.js) bei Scroll solid
   (`.is-scrolled`). Ohne den Modifier = solide Sandbar.
