The container has had one owner since the Quadlet cutover
(dankserver/jellyfin/quadlet/jellyfin.container). The block was a second owner,
and wrong on every path: jellyfin/jellyfin:latest instead of the pinned ghcr
image, /opt/jellyfin/* data roots that no longer exist, and a read-only
/mnt/entropy:/data bind that the metadata view has since replaced.
The planner no longer counts jellyfin as a compose service, so editing the
inventory cannot restart a media server; tests/deployment_scoping.bats pins that
contract for both jellyfin and plex.
