// Klassische Menüleiste (Bearbeiten/Ansicht/Fenster) neben der Wortmarke in
// der TopBar — ergänzt die bestehende Quick-Access-Icon-Leiste um textuelle
// Menüs im Rhino-/Desktop-Stil. Reine Darstellung + Callbacks (voll gesteuert,
// wie die übrige TopBar); jeder Eintrag ruft eine bereits existierende
// App.tsx-Funktion auf (kein Dummy-/Platzhalter-Eintrag).
//
// Bezeichner englisch, UI-Text über i18n (CONVENTIONS.md).
