Document npm registry mirror and Docker named volumes for builds

Per Issue #2, the static build workflow now consistently uses:
- npm_config_registry env var to switch to npmmirror (China mainland)
- duoji-node-modules named volume (replaces --tmpfs to avoid noexec)
- duoji-npm-cache named volume (faster subsequent installs)
- npm ci --no-audit --no-fund (faster CI/deploy)
- caddy reload note: bind mounts require docker-compose up -d caddy
- volume cleanup commands (docker volume rm ...)

+# 高徳乐 AI 舵机选型助手：静态部署说明
+
+本项目提供纯静态构建方式。产品数据、图片、选型计算、筛选和弹窗交互都在浏览器中运行；网站运行时不需要 Node.js、数据库、API 或 Cloudflare Worker。
+
+## 当前服务器的推荐方案
+
+服务器已经有 Docker Compose 管理的 Caddy 网关，并且 Caddy 占用 80/443 端口。因此本项目应当：
+
+1. 使用 `npm run build:static` 生成 `dist-static/`。
+2. 将 `dist-static/` 同步到服务器静态目录。
+3. 把静态目录以只读方式挂载到现有 Caddy 容器。
+4. 在现有 Caddyfile 中增加 `duoji.dbpi.com.cn` 的站点配置。
+
+不要为本项目另起 Nginx，不要让新容器绑定 80/443，也不要改动现有 `galderma-api` 和 `galderma-db` 容器。
+
+## 给 Git AI 的部署任务
+
+可以直接把下面这段话发给仓库里的 AI：
+
+> 请把本仓库部署为 `duoji.dbpi.com.cn` 的纯静态网站。不要执行 `npm run build`，不要启动 Vinext Server、Node.js 后端或 Cloudflare Worker；请执行 `npm run build:static`，发布生成的 `dist-static/` 目录。服务器已有 Docker Compose 管理的 Caddy 网关，80/443 端口不能抢占，也不要启动独立 Nginx 或新的 80 端口容器。请先检查现有 `/root/galderma/docker-compose.yml` 和 Caddyfile，在 Caddy 服务中增加只读挂载 `/var/www/duoji:/srv/duoji:ro`，并增加仓库 `deploy/Caddyfile.duoji` 中的站点配置。构建时服务器没有 Node.js，使用一次性 `node:22-alpine` 容器构建，并通过环境变量 `npm_config_registry=https://registry.npmmirror.com` 切换到中国大陆 npm 镜像（官方源经常连不上）；用两个 Docker named volume 分别隔离 `node_modules`（`duoji-node-modules`，解决 `tmpfs` 默认 `noexec` 导致 esbuild 执行失败的问题）和 npm 缓存（`duoji-npm-cache`，加快后续依赖安装）。修改前备份 Caddy 配置，修改后先校验配置，再只重载 Caddy；bind mount 改动必须重启 caddy 容器才生效（`caddy reload` 不会重挂 volume），实际影响约 3 秒。不要改动 galderma-api、galderma-db 和现有站点，不要把密码、SSH 密钥或 token 写入仓库。最后用 curl 检查首页、产品图片和 HTTPS。
+
+## 构建静态文件
+
+如果服务器有 Node.js：
+
+```bash
+npm ci --no-audit --no-fund
+npm run build:static
+```
+
+如果服务器没有 Node.js，使用一次性 Docker 构建容器。该方式不会在宿主机留下 `node_modules`，并通过环境变量切换 npm 镜像源以适配中国大陆网络环境：
+
+```bash
+docker volume create duoji-node-modules
+docker volume create duoji-npm-cache
+
+docker run --rm \
+  -v "$PWD":/src \
+  -v duoji-node-modules:/src/node_modules \
+  -v duoji-npm-cache:/root/.npm \
+  -w /src \
+  -e npm_config_registry=https://registry.npmmirror.com \
+  node:22-alpine \
+  sh -lc 'npm ci --no-audit --no-fund && npm run build:static'
+```
+
+### 为什么这样设计
+
+- **`npm_config_registry` 环境变量** 而不是 `npm config set`：避免在仓库或容器里写死镜像配置；非中国大陆环境不传这个环境变量就自动走官方源。
+- **named volume `duoji-node-modules`** 替代 `--tmpfs`：tmpfs 默认 `noexec`，会导致 esbuild 的 postinstall 可执行文件无法运行；named volume 既隔离宿主机又支持可执行权限。
+- **named volume `duoji-npm-cache`** 缓存 `/root/.npm`：第二次及以后的构建会复用缓存，`npm ci` 显著加快（从几十秒降到几秒）。注意：`npm ci` 仍会重建 `node_modules`（不修改 package-lock），加速主要来自缓存元数据；`node_modules` volume 主要用来隔离宿主机并解决执行权限问题。
+- **`--no-audit --no-fund`**：跳过 npm 审计和赞助信息，加快 CI/部署速度。
+
+### 清理构建缓存
+
+需要彻底清理时执行：
+
+```bash
+docker volume rm duoji-node-modules
+docker volume rm duoji-npm-cache
+```
+
+构建完成后，网站文件位于 `dist-static/`，入口是 `dist-static/index.html`。当前静态入口不依赖 `app/layout.tsx` 的动态 metadata，因此不要用 `npm run build` 代替 `npm run build:static`。
+
+## 与现有 Caddy 共存
+
+### 1. 同步静态文件
+
+以下路径是示例，实际执行时让部署 AI 先确认服务器目录和权限：
+
+```bash
+sudo mkdir -p /var/www/duoji
+sudo rsync -a --delete dist-static/ /var/www/duoji/
+```
+
+### 2. 给 Caddy 服务增加只读目录挂载
+
+在现有 Docker Compose 的 Caddy 服务中增加：
+
+```yaml
+volumes:
+  - /var/www/duoji:/srv/duoji:ro
+```
+
+不要覆盖原有 volumes；只追加这一项。容器内的 `/srv/duoji` 对应本项目的静态文件目录。
+
+### 3. 增加 Caddy 站点
+
+将 [`deploy/Caddyfile.duoji`](deploy/Caddyfile.duoji) 的内容追加到现有 Caddyfile。配置核心如下：
+
+```caddy
+duoji.dbpi.com.cn {
+    root * /srv/duoji
+    encode gzip zstd
+    try_files {path} /index.html
+    file_server
+}
+```
+
+修改前先备份 Caddyfile，并确认没有同名的 `duoji.dbpi.com.cn` 配置。修改后先验证：
+
+```bash
+docker exec galderma-caddy-1 caddy validate --config /etc/caddy/Caddyfile --adapter caddyfile
+```
+
+由于新增了 bind mount `/var/www/duoji:/srv/duoji:ro`，**必须重启 Caddy 容器才会挂载**（`caddy reload` 不会重新挂载 volume），执行：
+
+```bash
+cd /root/galderma
+docker-compose up -d caddy
+```
+
+实际影响约 3 秒，仅重启 Caddy，galderma-api / galderma-db 容器不受影响。如果现有容器内的 Caddyfile 路径不同，以 Docker Compose 的实际挂载路径为准。不要为了部署本项目执行整个 Compose 栈的重建或清理操作。
+
+### 4. 验证
+
+```bash
+curl -I https://duoji.dbpi.com.cn/
+curl -I https://duoji.dbpi.com.cn/catalog-products/precision-gears/418.jpg
+curl -I https://duoji.dbpi.com.cn/catalog-products/precision-gears-size/418.jpg
+```
+
+浏览器中再检查首页、`#selector`、`#products` 和 `#precision-gears`，并打开任意精密齿轮产品确认"产品尺寸"可以切换。
+
+## 后续更新
+
+首次部署后已经创建了 `duoji-node-modules` 和 `duoji-npm-cache` 两个 named volume，后续更新直接复用：
+
+```bash
+git pull --ff-only origin main
+
+docker run --rm \
+  -v "$PWD":/src \
+  -v duoji-node-modules:/src/node_modules \
+  -v duoji-npm-cache:/root/.npm \
+  -w /src \
+  -e npm_config_registry=https://registry.npmmirror.com \
+  node:22-alpine \
+  sh -lc 'npm ci --no-audit --no-fund && npm run build:static'
+
+sudo rsync -a --delete dist-static/ /var/www/duoji/
+```
+
+只更新静态文件时不需要重新构建或清理其他业务容器，也不需要重启 Caddy 容器（Caddy 的 `file_server` 每次请求都会读磁盘，新文件一上来就生效）。仅当 `docker-compose.yml` 或 Caddyfile 本身有改动时才需要 `docker-compose up -d caddy`。
+
+## 其他部署方式
+
+仓库中的 [`Dockerfile.static`](Dockerfile.static) 和 [`deploy/nginx-static.conf`](deploy/nginx-static.conf) 可用于独立服务器或独立容器场景，但不适用于当前已经由 Caddy 占用 80/443 的服务器。当前服务器优先使用"静态文件 + 现有 Caddy"方案。
+
+## 注意事项
+
+- 静态版的"申请样品"和"联系我们"表单目前只在浏览器中生成演示编号，不会将线索写入 CRM 或数据库。
+- 如果后续要保存客户线索，需要另行接入表单 API、企业微信、CRM 或数据库，不要把密钥写进前端代码。
+- 页面使用根路径资源，建议部署在域名根路径，不建议直接部署到 `/servo/` 子目录。
+- 目前尺寸图仅在产品详情弹窗切换到"产品尺寸"时加载，图片体积主要影响磁盘和用户主动查看尺寸图时的下载，不会首屏一次性加载全部图片。
