# One-off experiment: how are service containers reached on THIS runner?
#
# GitHub-hosted runners port-map services to localhost. Gitea Actions runs the
# job inside a container, so `localhost` is the job itself and services are
# reached by their service NAME. Several migrated workflows hardcode
# localhost:5432 — before rewriting any of them, prove which form actually
# works here instead of assuming.
