  playground-theme.css — shared visual layer for playground.php / demo.php / registry.php.
  Static, database-free. Resolves playground-scoped vars from the site palette defined in
  style.css (which switches via html[data-theme="dark"]). No PHP, no DB.
  Linked AFTER /assets/style.css so playground vars win where they overlap.
