# ============================================================
# NextStep — DEVELOPMENT overrides (use with docker-compose.yml)
#   docker compose -f docker-compose.yml -f docker-compose.dev.yml up
#   (add --build only after changing a Dockerfile, requirements.txt or package.json)
#
# - Every service is reachable from your machine (see ports below)
# - Backend, agents and frontend reload on code changes (source mounted)
# - Keycloak runs in dev mode
