/* ============================================================================
   ASCENT LEXICON — styles for the searchable vocabulary component
   ----------------------------------------------------------------------------
   Mount point:  <div data-course-lexicon></div>
   Renderer:     /assets/js/course-lexicon.js
   Data:         /assets/data/course-lexicon.json

   Colour rules: every colour is an existing studio token (with a fallback
   for hosts that scope their own palette, like Note Studio). Course chips
   reuse the per-course accent tokens that studio-tokens.css already
   contrast-verifies in both the dark theme and the .light-band daylight scope.
   Course is never the only signal — the chip text names the course.
