# Publishes the multi-arch Acauã image (linux/amd64 + linux/arm64) to the Gitea
# container registry. A merge into main publishes `edge`; a v* tag re-points the
# image already built for the same inputs to X.Y.Z, X.Y and latest (no rebuild)
# and creates the Gitea Release. Needs the secret REGISTRY_TOKEN (Gitea token
# with write:package) visible to this repository.
