# Gitea Actions: builds and pushes the multi-arch MeterVault image on a vX.Y.Z tag (SDD §11).
# Pushes to the Gitea container registry on this host. Requires a Docker-capable act_runner and
# a token with package:write — the built-in ${{ github.token }} works if the runner is configured
# to allow package writes; otherwise set a PACKAGES_TOKEN secret (a PAT with write:package).
