/* ============================================================
   Data-driven play theme (Phase 42)
   One template for every look. Driven entirely by the inline
   :root variables play.php injects per story:
     --bg  --text  --accent  --font  --font-heading  --base-size
   Every bespoke shade (surfaces, glows, button text, scrollbar)
   is DERIVED from those few values with color-mix() — small data,
   still hand-tuned in feel. Structure mirrors the legacy
   themes/*_theme.css files so the play markup is unchanged.
