   --------------------------------------------------------------------------
   All visual styling of the BO lives in this one file. The PHP pages only use
   the semantic class names listed below (no inline styles), so to give the BO a
   brand new look, replace this file with a new one that styles the same classes.

   Quick tweaks: change the variables in :root (colors, radius, blur, font...).

   Fonts & icons are self-hosted in css/vendor/ (Poppins + Remix Icon "ri-*").
