/* =============================================================
   Sidebar-Menü (Burger + Off-Canvas-Drawer von rechts)
   Übernommen aus dem JanMaxLive-Muster: fixierter Burger oben rechts,
   Drawer schiebt sich rein, der Seiteninhalt gleitet mit zur Seite.

   Unterschied zu JanMaxLive: dort ist es Mobile-only (Desktop hat eine
   Nav-Pill). FBC hat keine Desktop-Navigation, deshalb gilt es hier auf
   allen Größen. Der Theme-Umschalter sitzt unten im Drawer.
