/* WTB Büro – eigenes Design-System.
   Farben und Schriften aus dem wetastebetter-theme (style.css) uebernommen,
   damit die Buchhaltung zur Marke passt statt nach Bootstrap-Default auszusehen.
   Bewusst NICHT wie die Lager-App: dort reicht eine Top-Navbar, hier kommen
   noch Belege, Bank, Steuern, Auswertungen und Einstellungen dazu - das
   skaliert nur mit einer Sidebar. */
