# Wrapping the release actions: docker/login-action with docker/build-push-action,
# and goreleaser/goreleaser-action. Releases are where a CI workflow has effects,
# so every wrapper here is `cache = False` (a pass says nothing about a
# publish that must happen) and the steps exist only for a tag.
#
# starci has no way yet to hand a step a secret. The empty `env` values below
# only name what each step needs; getting a real value to them is up to
# whatever runs the step, so treat this as the shape of the wrapper and not as
# something to run as it is.
