# Two merges landing seconds apart each start a build, and whichever finishes

# Superseding runs on the same ref cancels the stale one so :dev always tracks
# the newest push. Releases are keyed by their own ref and aren't affected.

# requests only Docker media types, so an OCI-only manifest returns 404
# and the container reports "not available" instead of an update status.
# provenance: false alone isn't enough — buildx still emits OCI types.
