#   dev  - 本機開發（docker 起 Mongo/Redis，go run / vite dev）
#   prod - 建置產物（前端 dist + linux Go binary），並可部署成 systemd 服務 + nginx

# 常用：
#   make dev-infra         # 起本機 Mongo/Redis
#   make dev-backend       # 跑 gateway (:8890)
#   make dev-frontend      # 跑前端 (:5173，proxy 到 :8890)
#   make build             # 產出 frontend/dist + backend/bin/{gateway,worker}
#   sudo make install      # 部署到目標主機（見 infra/README.md）
