/* ----------------------------------------------------------------------
   dogbar visual system — a dark, streaming-app layout: fixed top bar,
   left category rail, poster grid. All colours, radii and shadows live
   as --bb-* tokens on :root.

   - accent is dogbar blue (#2f7dff): brand mark plus every interactive
     / selected cue. Everything else is greyscale for depth.
   - cards are 2:3 portrait — MacCMS vod_pic art is portrait poster art.
   - body text in Plus Jakarta Sans, brand/headings in Sora, both
     self-hosted (see fonts.css); CJK falls back to the system font.
