+# 推荐用法：
+#   cp .env.local .env   # 本机开发，连接 localhost 基础设施
+#   cp .env.remote .env  # 本机开发，连接远程基础设施（如 192.168.1.173）
+#
+# 注意：
+#   1. .env 文件不会被提交到仓库（已在 .gitignore 中忽略）。
+#   2. scripts/local-up.sh 启动 docker-compose 时，会自动把 host 覆盖为容器名，
+#      因此无论 .env 中是 localhost 还是远程 IP，docker-compose 内部都能正确互联。
+#   3. 若手动执行 docker compose，请确保当前 .env 中的 MYSQL_HOST/REDIS_HOST/
+#      RABBITMQ_HOST 指向可访问地址，或使用 local-up.sh 启动。
