# 构建参数默认走国内源；可在项目根 .env 中覆盖（Compose 会自动加载 .env）
# 基础镜像 postgres/nginx/python/node 仍从 Docker Hub 拉取，请在 Docker Desktop 配置 registry-mirrors（见 scripts/configure-mirrors.sh）
#
# backend 已默认清空 HTTP(S)_PROXY，避免宿主机/IDE 代理注入容器导致访问 dashscope 失败；若必须走代理访问外网，请用
# docker-compose.override.yml 覆盖 HTTPX_TRUST_ENV=1 并设置代理变量（见 .env.example 说明）
