This directory is the Pages-hosted artifact surface.

Put only the current, latest payloads here. Access is by the unlisted Pages URL,
so no magic header gate is used.

Use R2 for any OCI blob or other file that exceeds the Pages per-file limit,
and surface it through the same unlisted Cloudflare entrypoint.

R2 blobs are served from `/blobs/<key>` by the Pages Function in `functions/`.
The root `/` route redirects to this README.

OCI registry requests use `/v2/...` and are served by the Pages Functions in
`functions/v2/`. Repository-specific manifests live under
`artifacts/registry/<repo>/manifests/sha256/` and the current tag map lives in
`artifacts/registry/<repo>/index.json`.

The AG1 Omni image-source release metadata lives under
`artifacts/omni-image-source/`.
