name: Demo images

# Builds and pushes the public-demo images on every change to the UI / mock
# backend, so the separated `archy-demo` Portainer stack auto-tracks the real
# code (see demo-deploy/ and docs/demo-deployment-design.md).
#
# Required repo configuration:
#   vars.DEMO_REGISTRY        e.g. 146.59.87.168:3000/lfg2025
#   secrets.DEMO_REGISTRY_USER
#   secrets.DEMO_REGISTRY_TOKEN
# Optional:
#   secrets.PORTAINER_WEBHOOK  redeploy hook called after a successful push
