# deliberate prod step). Visible sequential jobs from most to least significant:
#   build -> deploy-main -> deploy-bot -> verify
# The per-service rolling (postgres->backend->gateway->landing->validator->caddy),
# health-gating and auto-rollback live in deploy/prod-deploy.sh on the main host and
# show in the deploy-main log. Manual post-deploy rollback is prod-rollback.yaml.
