   Geteilte obere Navigation (Landing + Report) — theme-aware über CSS-Variablen.
   Markup: templates/_site_nav.html.twig. Global geladen via assets/app.js.
   Mobile-Menü: natives <details> (kein JS). Umschaltpunkt ist 900px: die
   Desktop-Zeile (Marke + Sub + Links + CTA) braucht auf den Report-Seiten rund
   875px und schob bei 861px 14px horizontalen Seiten-Scroll auf JEDE
   Report-Seite — gefunden vom Breiten-Sweep, nicht von Hand. Wer hier Links
   ergänzt, fährt `node tests/Visual/breiten-sweep.mjs` erneut.
