Deployed from a browser

No terminal was opened to put this here.

Somebody signed in at platform.rayspec.ai, dropped a zip on a page, watched the job walk its phases, and this is what came out the other end.

1. the bundle went up in 512 KiB chunks, in order, resumable
2. the supervisor unpacked it in a container with no network
3. a gVisor-isolated container started serving it
4. the gateway obtained a certificate and routed the hostname

Phase 5.5b — deploy in the browser.
