/* =========================================================
   THS Class Gallery — front-end styles
   Design: warm "yearbook shelf" — espresso + coral on cream.
   Rewritten to match the actual renderer markup (thscg-class-btn,
   thscg-expand, thscg-section-btn/dot/count, thscg-grid, thscg-lightbox…).

   Root cause of the old bug: .thscg-section-dot was being rendered
   as a fixed-size circle, so longer section names ("Apples",
   "Mulberry") got clipped. Here .thscg-section-dot is just the label
   text inside a flexible pill button — width follows content, never
   a fixed circle.
