# Backend targets:
# - backend: Includes only the backend part. Can be used for development, does not support hot-reloading.
# - backend-hotreload: Support hot-reloading, used only for local deployment. Excludes frontend
#
# Frontend targets:
# - frontend-base: Common base for both deployment and development containers
# - frontend-dev: Target only for local development, supports hot-reload
# - frontend-build: Builds the frontend files that will be included with the backend for final production-ready container.
#
# The `combined` stage extends the `backend` target with files built in the `frontend-build` step. Includes everything, production-ready
