Server computes SHA-256 hash of all component source at startup.
Client signals its cached hash via cookie (sx-comp-hash). On full
page load: cookie match → server sends empty script tag with just
the hash; mismatch → sends full source. Client loads from
localStorage on hit, parses inline + caches on miss.

- Parse tw.css into per-class lookup registry at startup
- Pre-scan component CSS classes at registration time (avoid per-request regex)
- Compress SX-Css header: 8-char hash replaces full class list (LRU cache)
- Add ;@css comment annotation for dynamically constructed class names
- Safelist bg-sky-{100..400} in Tailwind config for menu-row-sx dynamic shades
- Client sends/receives hash, falls back gracefully on cache miss
