A fragment's tag rides in its markup too: Cloudflare strips etag from HTML #324

Seen on the live 0.7.42 forge: CSS kept its `etag` through Cloudflare, every HTML fragment lost it, so the conditional fetch never got a 304.

Seen on the live 0.7.42 forge: CSS kept its etag through Cloudflare, every HTML fragment lost it, so the conditional fetch never got a 304.

layout.fragment stamps the same hash on the fragment's first element as data-etag (of the unstamped body, so the server recomputes it the same way).
The client reads the header when it arrives and the attribute when it does not, and sends either back as if-none-match.
Test: the stamped attribute equals the header. docs/STUDIO.md says why.
