Static shell + dynamic RSC islands

The marketing-shaped content here is identical for everyone — so the SSR'd HTML can be cached at the edge (CF Cache-Control). The three boxes below are islands: each fetches a freshly-rendered RSC fragment on mount, so they show per-request data without breaking the shell's cacheability.

Edge-rendered platform

Built on Cloudflare Workers, every page response is served from the closest of 300+ PoPs worldwide. Static shells like this one are cached at the edge — TTFB measured in single-digit milliseconds globally. Dynamic data hydrates after the shell loads, so the user sees structure instantly and live numbers shortly after.

(Shell rendered at 3:15:49 AM on the client — but for SSR with cache headers, this would be a snapshot from the last cache write, not per-request.)

Reload the page — the shell text doesn't change, but the three island boxes show fresh data each time. If the shell were cached at the edge (Cache-Control: s-maxage=300), the only worker work per visit would be the three island fetches; everything else would be a CDN hit.
