   rauMKult — Handy-Menü als App-Menü (rk-mobilmenue.css)
   Version: 1.1 | 2026-10-01 | Spec 014: Kopf des Blatts nutzt --rk-sicher-oben (Rückfall env(safe-area-inset-top)).
   Version: 1.0 | 2026-09-30 | Runde 10 M2
   Vollbild-Blatt (Handy) bzw. Seitenblatt 420 px (ab 600 px), gruppierte Zeilen wie in einer App,
   Bereiche zum Hineintippen, Akkordeons darunter, Kontakt-Kurzwege unten.
   Eigenständig: hängt nur an den globalen Tokens (main-v2.css :root) — keine Abhängigkeit von
   anderen Runde-10-Änderungen. Überschreibt die alte Schubladen-Optik (.site-nav-overlay*) gezielt.
   Stapel: liegt über Cookie-Hinweis (9000), Schwebeknöpfen und Fortschrittsbalken (9100),
   unter dem Cookie-Einstellungsfenster (10000).
