| Rule | Detail |
|---|---|
| Referer allow-list | *.5457090.xyz and the bare domain. Everything else gets 403. |
| Immutable naming | Never reuse a URL with different content; deploys create new hashes. |
| No HTML | Static assets only — pages are served by the services themselves. |
| Purge path | ETag revalidation only; force a miss by changing the hash. |
