+# 高徳乐 AI 舵机选型助手：静态部署说明
+
+本仓库已经提供纯静态构建方式。页面的产品数据、图片、选型计算、筛选和弹窗交互都在浏览器中运行，不依赖 Node.js、数据库、API 或 Cloudflare Worker 的运行时。
+
+## 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：
+
+> 请将本仓库部署为纯静态网站，不要启动 Node.js 后端、Vinext Server 或 Cloudflare Worker。先执行 `npm ci`，再执行 `npm run build:static`。把生成的 `dist-static/` 目录作为网站根目录发布到当前云服务器，并配置 Nginx 将未知路径回退到 `index.html`。如果服务器使用 Docker，请使用仓库中的 `Dockerfile.static` 构建并运行，容器端口为 80。部署完成后检查首页、`#selector`、`#products` 和 `#precision-gears` 页面区域，以及产品图片是否能正常加载。
+
+## 方式一：Nginx / 静态文件服务器
+
+在服务器项目目录执行：
+
+```bash
+git clone https://git.databerrypi.com/MJ-IT/gdm-Servo-model.git
+cd gdm-Servo-model
+npm ci
+npm run build:static
+```
+
+将 `dist-static/` 下的全部文件复制到 Nginx 网站根目录，例如：
+
+```bash
+sudo mkdir -p /var/www/gdm-servo
+sudo rsync -a --delete dist-static/ /var/www/gdm-servo/
+```
+
+Nginx 的站点配置可以参考 [`deploy/nginx-static.conf`](deploy/nginx-static.conf)。其中最关键的是：
+
+```nginx
+root /var/www/gdm-servo;
+
+location / {
+    try_files $uri $uri/ /index.html;
+}
+```
+
+以后更新时，在仓库目录执行：
+
+```bash
+git pull --ff-only origin main
+npm ci
+npm run build:static
+sudo rsync -a --delete dist-static/ /var/www/gdm-servo/
+```
+
+运行时只需要 Nginx，不需要保留 Node.js 进程。
+
+## 方式二：Docker
+
+仓库已经提供 [`Dockerfile.static`](Dockerfile.static)：
+
+```bash
+docker build -f Dockerfile.static -t gdm-servo-static:latest .
+docker run -d --name gdm-servo-static --restart unless-stopped -p 80:80 gdm-servo-static:latest
+```
+
+如果服务器已有 80 端口服务，可以改成 `-p 8080:80`，再由现有 Nginx 反向代理到 `127.0.0.1:8080`。
+
+## 本地检查
+
+```bash
+npm run build:static
+python3 -m http.server 8080 --directory dist-static
+```
+
+然后打开 `http://服务器IP:8080`。不要直接双击 `index.html`，因为浏览器会限制本地文件加载模块和图片资源。
+
+## 部署注意事项
+
+- 静态版没有服务端接口；当前“申请样品”和“联系我们”表单只在浏览器中生成演示编号，不会把线索写入 CRM 或数据库。
+- 如果后续要真正保存客户线索，需要另行接入表单 API、企业微信、CRM 或数据库，不应把密钥写进前端代码。
+- 页面使用根路径资源（例如 `/catalog-products/...`），因此建议部署在域名根路径。如果必须部署到 `/servo/` 子目录，需要同步调整 Vite 的 `base` 和图片资源路径。
+- 每次产品数据或图片变更后，都要重新执行 `npm run build:static`，再同步整个 `dist-static/` 目录。

+## Static Deployment
+
+This project also supports a no-backend static build. Run `npm run build:static` and publish the generated `dist-static/` directory to Nginx, object storage, or another static file server. See [DEPLOY_STATIC.md](DEPLOY_STATIC.md) for instructions that can be handed directly to a Git AI deployment agent.

 This starter does not use `wrangler.jsonc`.
