------------------------------------------------------------------------------
 NOTE: This is a hand-authored, ready-to-use stylesheet — the theme works as
 soon as it's activated (Tailwind utility classes are resolved by the Play CDN
 loaded in header.php). For a purged production build, run `npm run build`,
 which regenerates this file from src/input.css + tailwind.config.js.
