+### 2. Python FastAPI 后端 (apps/api/)
+
+```

+├── main_api.py            # FastAPI主入口
+├── main.py -> ../../main.py  (符号链接)

+
+**API端点:**
+- `POST /api/v1/convert` - 创建转换任务
+- `GET /api/v1/jobs/{id}` - 查询任务状态
+- `GET /api/v1/jobs/{id}/result` - 下载结果
+- `DELETE /api/v1/jobs/{id}` - 取消任务
+- `WS /ws/jobs/{id}/progress` - 实时进度推送
+
+### 3. CI/CD 配置 (.github/workflows/)
+
+- `deploy-web.yml` - Vercel自动部署
+- `deploy-api.yml` - Railway/Fly.io自动部署
+
+### 4. 文档
+
+- `PROJECT-NEXTJS.md` - 项目说明
+- `.env.local.example` - 环境变量示例

+
+## 🚀 部署指南
+
+### 前端 → Vercel
+
+```bash
+# 安装Vercel CLI
+npm i -g vercel
+
+# 部署
+cd apps/web
+vercel --prod
+```
+
+**环境变量:**
+```
+NEXT_PUBLIC_API_URL=https://api.yoursite.com
+NEXT_PUBLIC_WS_URL=wss://api.yoursite.com
+```
+
+### 后端 → Railway
+
+```bash
+# 安装Railway CLI
+npm i -g @railway/cli
+
+# 部署
+cd apps/api
+railway login
+railway init
+railway up
+```
+
+### 后端 → Fly.io
+
+```bash
+# 安装Fly CLI
+brew install flyctl
+
+# 部署
+cd apps/api
+flyctl launch
+flyctl deploy
+```
+
+---
+
+## 🏃 本地开发
+
+```bash
+# 1. 启动Python后端
+cd apps/api
+pip install -r requirements.txt
+python main_api.py
+
+# 2. 启动Next.js前端 (新终端)
+cd apps/web
+npm install
+npm run dev
+
+# 3. 访问 http://localhost:3000
+```

+## ⚠️ 注意事项
+
+1. **Python后端无法部署到Vercel**，因为Vercel只支持Node.js运行时
+2. 推荐部署方案:
+   - 前端: **Vercel** (免费)
+   - 后端: **Railway** 或 **Fly.io** (有免费额度)
+3. SAM3模型需要GPU，确保后端部署在支持GPU的平台上
+4. 需要配置环境变量 `NEXT_PUBLIC_API_URL` 指向后端地址
