/* ==========================================================================
   peel-chat.css — additive styles for the Peel page's ONE system: clicking
   the cube. Holds the topic picker (loads any tree into the cube), the recall
   glow on a clicked cell, and the real connector graph shown for that cell.
   No conversational chat. Uses dive.css tokens (--ink/--muted/--blue/--green/
   --purple/--line/--radius/--teal/--dim/--panel). Nothing here changes the
   resting cube; the .cube-glow rules only fire when the render loop lights a
   recalled cell. Fully offline — no external assets.
