# Build backend/frontend images, push to Gitea Container Registry, deploy with pull-only compose.
#
# Repository Variables (Settings → Actions → Variables) — non-secret:
#   REGISTRY_HOST        e.g. 178.131.50.201:3000   (no http/https)
#   REGISTRY_OWNER       Gitea user or org that owns the packages (same as image namespace)
#   PUBLIC_BASE_URL      URL users open in browser, e.g. http://178.131.50.201:8088  (no trailing slash)
#
# Repository Secrets (Settings → Actions → Secrets):
#   REGISTRY_USERNAME    Gitea username for docker login
#   REGISTRY_PASSWORD    Gitea access token (packages:read/write) or account password
#
# Optional:
#   STAGING_HTTP_PORT       host port for nginx (default 8088)
#
# Required for deploy job (absolute path on the runner host):
#   DEPLOY_SECRETS_DIR      folder containing database.staging.env + backend.staging.env
#
# Runner: self-hosted with Docker. Default shell is powershell (Windows act_runner often has no WSL bash).
# For a Linux runner, change defaults.run.shell to bash and restore bash syntax if needed.
#
# We do NOT use gitea.com/actions/checkout — many restricted networks cannot reach gitea.com.
# Checkout is a plain git clone from the same Gitea host.
