# Build and push Docker images to Gitea registry on push to main.
# Requires: Repository Actions enabled; secrets REGISTRY_USER and REGISTRY_TOKEN (PAT with package write);
#           a runner with Docker (e.g. act_runner with Docker, or host Docker socket).
# Registry is assumed to be the same Gitea host; set REGISTRY in repo variables if different.
