/* 15-sidebar.css - Zijbalk: kop met zoekveld, uitklapbare groepen, gebruikerskaart.
   Styling van de nieuwe zijbalk (shadcn-achtige opmaak) op de bestaande tokens.

   Let op: omdat dit bestand ná 01-base.css laadt, staat de hover-fix voor de
   actieve tab (.nav-btn.active:hover) hieronder en niet in 01-base.css. */
