# x0gp PoC server Makefile
#
# Common targets:
#   make tidy      - go mod tidy
#   make build     - compile poc-server (linux/arm64 by default for Orange Pi 5 Pro)
#   make run       - build + run locally (dev mode, port 8080)
#   make proto     - regenerate Go from proto/ via Docker
#   make test      - go test ./...
#   make lint      - go vet + (optional) golangci-lint
#   make docker    - build the api-gateway image
#   make compose   - run dev stack (postgres + redis + prometheus + grafana + api-gateway)
