/* ACONA AI Hub — Design-System "Console"
   Dunkel als Standard, helles Theme per Umschalter (data-theme auf <html>, serverseitig gesetzt, kein Aufblitzen).
   Geist für die Arbeitsoberfläche, Poppins (ACONA-CI) für Marke und Seitentitel, Geist Mono für Code und Keys.
   Zwei neutrale Ebenen: Chrome (Kopfleiste, Navigation) und Arbeitsfläche. Elevation über 1px-Linien,
   Schatten nur für schwebende Ebenen (Menüs, Dialoge, Toasts). */
