+# 项目技术规范
+
+> 个人偏好已在全局规则 `~/.cursor/rules/personal-preferences.mdc` 中定义
+
+---
+
+## 一、视觉设计标准（苹果风格）
+
+### 核心原则
+
+| 原则 | 说明 |
+|------|------|
+| 内容至上 | UI 退后，内容向前，拒绝无意义装饰 |
+| 物理感材质 | 使用 Liquid Glass、Spring Animation、柔和阴影 |
+| 优雅排版 | 大标题收紧字间距，正文标准，小字加宽 |
+
+### 色彩系统
+
+| 用途 | Light Mode | Dark Mode |
+|------|------------|-----------|
+| 背景 | `#FFFFFF` | `#000000` |
+| 次级背景 | `#F5F5F7` | `#1C1C1E` |
+| 主文本 | `#1D1D1F` | `#F5F5F7` |
+| 次文本 | `#86868b` | `#86868b` |
+| 品牌色 | `#008D74` | `#00B896` |
+
+### 排版系统
+
+- **字体栈**：`-apple-system, BlinkMacSystemFont, "SF Pro Display", system-ui`
+- **Tailwind 类**：`font-apple-system`、`tracking-apple-tighter`
+- **组件**：`Typography`（LargeTitle, Title1, Body, Caption1）
+
+### 去 AI 味专项
+
+| 禁止 | 推荐 |
+|------|------|
+| ❌ 均等分布（4个功能各占25%） | ✅ 非对称布局 |
+| ❌ 默认实心图标 | ✅ 细线条 stroke-width 1.5 |
+| ❌ 彩虹渐变背景 | ✅ 纯色/微妙渐变 |
+| ❌ Lorem Ipsum 占位 | ✅ 真实场景数据 |
+
+---
+
+## 二、技术栈与版本
+
+### 核心依赖（2026-01-30）
+
+| 类别 | 依赖 | 版本 |
+|------|------|------|
+| 框架 | Next.js | 16.1.6 |
+| UI | React | 19.2.4 |
+| 样式 | Tailwind CSS | 4.1.18 |
+| ORM | Prisma | 7.3.0 |
+| 验证 | Zod | 4.3.6 |
+| 3D | Three.js | 0.182.0 |
+| 3D | @react-three/fiber | 9.5.0 |
+| 3D | @react-three/drei | 10.7.7 |
+
+### 基础服务（Docker）
+
+| 服务 | 镜像 | 端口 |
+|------|------|------|
+| PostgreSQL | postgres:15-alpine | 5432 |
+| Redis | redis:7-alpine | 6379 |
+| MinIO | minio/minio:latest | 9000/9001 |

+```
+
+---
+
+## 四、开发规范
+
+### API 响应格式标准
+
+**所有 API 必须使用统一的响应格式：**
+
+| 操作类型 | 响应格式 | 示例 |
+|----------|----------|------|
+| 列表查询 | `{ items: [], pagination: {} }` | `{ items: [...], pagination: { page, limit, total, hasMore } }` |
+| 详情/创建/更新 | `{ data: {} }` | `{ data: { id, name, ... } }` |
+| 删除 | `{ success: true }` | `{ success: true }` |
+| 错误 | `{ error: { code, message } }` | `{ error: { code: 'VALIDATION_FAILED', message: '...' } }` |
+
+**前端调用示例：**
+```typescript
+// 列表
+const { items, pagination } = await response.json()
+
+// 详情
+const { data } = await response.json()
+```
+
+### UI 元组件体系
+
+**必须使用元组件，禁止直接写原生 HTML 表单元素！**
+
+| 元组件 | 路径 | 用途 |
+|--------|------|------|
+| `Button` | `@/components/ui/Button` | 所有按钮 |
+| `Input` | `@/components/ui/Input` | 单行输入框 |
+| `Textarea` | `@/components/ui/Input` | 多行输入框 |
+| `Select` | `@/components/ui/Select` | 下拉选择框 |
+| `Modal` | `@/components/ui/Modal` | 弹窗 |
+| `Card` | `@/components/ui/Card` | 卡片容器 |
+| `Badge` | `@/components/ui/Badge` | 标签徽章 |
+| `Toast` | `@/components/ui/Toast` | 全局气泡提示 |
+
+**Toast 使用方法：**
+```tsx
+import { useToast, ToastContainer } from '@/components/ui/Toast'
+
+// 在组件中
+const toast = useToast()
+
+// 显示提示
+toast.success('操作成功')
+toast.error('操作失败')
+toast.warning('警告信息')
+toast.info('提示信息')
+
+// 在 JSX 中添加容器
+<ToastContainer toasts={toast.toasts} onClose={toast.removeToast} position="top" />
+```
+
+**聚焦样式统一为品牌色边框（无光晕）：**
+- 边框：`#008D74`（2px 实线）
+- 禁止使用 `box-shadow` 作为聚焦光晕
+- 全局 CSS 已设置兜底样式，但仍应优先使用元组件
+
+### 组件样式规范
+
+| 属性 | 规范 |
+|------|------|
+| 背景色 | `#F5F5F7`（浅灰）|
+| 聚焦边框 | `#008D74`（品牌色）|
+| 圆角 | `rounded-apple-md`（10px）或 `rounded-apple-lg`（16px）|
+| 字体 | `font-apple-system tracking-apple-tighter` |
+
+### 动画规范
+
+| 场景 | 时长 | 缓动函数 |
+|------|------|---------|
+| 展开 | 500ms | `cubic-bezier(0.32, 0.72, 0, 1)` |
+| 收起 | 350ms | `cubic-bezier(0.32, 0, 0.68, 0)` |
+| 按钮按压 | 100ms | `scale(0.98)` |
+| 悬停放大 | 200ms | `scale(1.02)` |
+
+### API 响应格式
+
+```typescript
+interface ApiResponse<T> {
+  success: boolean
+  data?: T
+  error?: {
+    code: string       // AUTH_001, PRODUCT_001
+    message: string    // 用户友好信息
+    details?: object   // 仅开发环境
+  }
+  meta?: {
+    timestamp: string
+    requestId: string
+    pagination?: { page, limit, total, hasMore }
+  }
+}
+```
+
+### API 路由模式
+
+```typescript
+export async function GET(request: NextRequest) {
+  return handleRequest(request, async (ctx) => {
+    const data = await productService.getProducts(ctx.user.id, ctx.query)
+    return success(data)
+  })
+}
+```
+
+### 缓存策略
+
+| 数据类型 | TTL | 失效策略 |
+|---------|-----|---------|
+| 用户信息 | 5分钟 | 更新时失效 |
+| 产品详情 | 5分钟 | 更新/删除时失效 |
+| 产品列表 | 2分钟 | 任何变更失效 |
+| 主题配置 | 10分钟 | 激活/更新时失效 |
+
+---
+
+## 五、禁止事项
+
+| 禁止使用 | 替代方案 |
+|---------|---------|
+| `text-gray-*` | `text-apple-label-*` |
+| `bg-gray-*` | `bg-apple-bg-*` |
+| `shadow-*` | `shadow-apple-*` |
+| 蓝色 focus ring | 品牌色 `#008D74` |
+
+---
+
+## 六、核心原则
+
+1. **视觉效果优先，性能优化次之**
+2. **不动已调整好的视觉效果** - 已确定的元组件样式保持不变
+3. **优先使用元组件** - 所有页面必须复用 `src/components/ui/` 下的组件
+4. **改元组件 = 全局生效** - 修改元组件或设计令牌，全局自动更新
+
+---
+
+## 七、功能入口
+
+| 功能 | 路径 |
+|------|------|
+| 首页 | `/` |
+| 登录 | `/login` |
+| 产品列表 | `/products` |
+| SKU 详情（分享页） | `/share/[token]` |
+| 主题管理 | `/admin/themes` |
+| 主题公开接口 | `GET /api/themes/current` |
+
+---
+
+## 八、环境变量
+
+```bash
+# 数据库
+DATABASE_URL=postgresql://user:pass@localhost:5432/furniture_db
+
+# Redis
+REDIS_URL=redis://127.0.0.1:6379
+
+# 认证
+NEXTAUTH_SECRET=your-secret-key
+NEXTAUTH_URL=http://localhost:3000
+
+# MinIO
+MINIO_ENDPOINT=localhost
+MINIO_PORT=9000
+MINIO_ACCESS_KEY=minioadmin
+MINIO_SECRET_KEY=minioadmin
+```
+
+---
+
+## 九、文件存储架构
+
+### 存储方式：本地文件系统 + MinIO
+
+由于不使用云存储（AWS S3/阿里云 OSS），采用自建服务器部署方案：
+
+```
+public/uploads/           # Next.js 静态托管（开发/小规模）
+├── models/
+│   ├── demo/             # 演示模型
+│   └── {productId}/      # 按产品ID组织
+│       ├── original/     # 原始上传文件（DWG等）
+│       └── model.glb     # 转换后的 3D 模型
+└── thumbnails/           # 缩略图
+
+MinIO Bucket: furniture-files/   # 生产环境存储
+├── models/
+│   └── {productId}/
+│       ├── original/xxx.dwg
+│       └── model.glb
+└── thumbnails/
+```
+
+### MinIO 硬盘要求
+
+| 项目 | 说明 |
+|------|------|
+| 硬盘类型 | **机械硬盘完全支持**，无特殊要求 |
+| 最低配置 | 单盘模式，无需 RAID |
+| 推荐配置 | 多盘分布式（可选，提升可靠性） |
+| 文件大小 | DWG 一般 < 1MB，转换后 GLB < 5MB |
+| 性能考量 | 3D 模型加载主要受网络带宽限制，硬盘 I/O 不是瓶颈 |
+
+### 数据库存储字段
+
+```
+Product.modelUrl     = "/uploads/models/{productId}/model.glb"
+Product.thumbnailUrl = "/uploads/thumbnails/{productId}.jpg"
+ProductSKU.modelUrl  = null（继承产品模型）或独立路径
+```
+
+---
+
+## 十、内外网流量架构
+
+### 部署场景
+
+生产服务器部署在公司内网，通过内网穿透服务对外提供访问。
+
+### 流量分离架构
+
+```
+                          公司内网
+    ┌────────────────────────────────────────────────┐

+    │                              └─────▲─────┘     │
+    │                                    │           │

+    └─────────┼──────────────────────────────────────┘
+              │
+              ▼
+    ┌─────────────────┐
+    │  frp server     │  ← 公网服务器 / 云主机
+    │  (穿透服务)      │
+    └────────▲────────┘
+             │
+    公网用户 ─┘
+```
+
+### 双入口方案
+
+| 用户类型 | 访问地址 | 路径 | 速度 |
+|---------|---------|------|------|
+| 内网用户 | `http://192.168.x.x:3000` | 直连服务器 | ⚡ 快 |
+| 外网用户 | `http://xxx.frp.io` | 穿透隧道 | 🐢 较慢 |
+
+**特点：**
+- 配置简单，无需内网 DNS
+- 内网用户访问内网地址，外网用户访问穿透域名
+- 应用代码无需修改
+
+### 穿透工具：frp（免费开源）
+
+需要一台有公网 IP 的服务器（云主机/VPS）
+
+### 外网访问策略
+
+| 功能 | 公网是否可访问 | 说明 |
+|------|---------------|------|
+| 分享链接 `/share/[token]` | ✅ 是 | 无需登录，通过 token 验证 |
+| 登录页 `/login` | ✅ 是 | 密码验证 |
+| 管理后台 `/admin/*` | ⚠️ 受限 | 需登录 + 角色验证 |
+| API 接口 | ⚠️ 受限 | JWT + Rate Limit |
+| 静态资源 `/uploads/*` | ✅ 是 | 3D 模型/图片 |
+
+### 安全措施
+
+1. **Rate Limiting** - 外网 API 限流（如 100次/分钟）
+2. **分享链接过期** - 支持设置有效期
+3. **frp 访问密码** - 穿透服务可配置访问密码
+4. **HTTPS** - 外网建议配置 HTTPS（frp 支持）
+
+### 内网服务器配置
+
+```bash
+# 硬件配置（适合中小规模）
+- CPU: 4核+
+- 内存: 8GB+
+- 硬盘: 机械硬盘 500GB+（模型存储，无特殊要求）
+- 内网带宽: 100Mbps+（内网用户快速访问）
+
+# 服务端口（仅内网监听）
+- Next.js: 3000
+- PostgreSQL: 5432
+- Redis: 6379
+- MinIO: 9000
+```
+
+### frp 配置示例
+
+**frps.toml（公网服务器）**
+```toml
+bindPort = 7000
+vhostHTTPPort = 80
+vhostHTTPSPort = 443
+```
+
+**frpc.toml（内网服务器）**
+```toml
+serverAddr = "公网服务器IP"
+serverPort = 7000
+
+[[proxies]]
+name = "furniture-web"
+type = "http"
+localIP = "127.0.0.1"
+localPort = 3000
+customDomains = ["furniture.yourdomain.com"]

+
+---
+
+## 快速部署
+
+### 1. 克隆项目
+```bash
+git clone <repository-url>
+cd furniture-3d-system
+```
+
+### 2. 配置环境变量
+```bash
+# 复制配置模板
+cp .env.example .env
+
+# 编辑配置（重要！必须修改默认密码）
+nano .env
+```
+
+### 3. 启动服务
+```bash
+# 标准模式（推荐，8GB+ 内存）
+docker-compose -f docker-compose.prod.yml up -d
+
+# 轻量级模式（4-8GB 内存）
+docker-compose -f docker-compose.lightweight.yml up -d
+```
+
+### 4. 初始化数据库

+openssl rand -base64 32
+
+# 或使用 Node.js
+node -e "console.log(require('crypto').randomBytes(32).toString('base64'))"
+```
+
+### 完整配置示例
+```env
+# ============================================
+# 数据库配置
+# ============================================
+DB_USER=postgres
+DB_PASSWORD=<生成的强密码>
+DB_NAME=furniture3d
+DB_PORT=5432
+DATABASE_URL=postgresql://${DB_USER}:${DB_PASSWORD}@postgres:5432/${DB_NAME}
+
+# ============================================
+# Redis 缓存配置
+# ============================================
+REDIS_URL=redis://redis:6379
+# 如需密码认证：
+# REDIS_URL=redis://:${REDIS_PASSWORD}@redis:6379
+
+# ============================================
+# MinIO 对象存储配置
+# ============================================
+MINIO_ROOT_USER=admin
+MINIO_ROOT_PASSWORD=<生成的强密码>
+S3_ENDPOINT=http://minio:9000
+S3_BUCKET=furniture-3d-models
+S3_ACCESS_KEY=${MINIO_ROOT_USER}
+S3_SECRET_KEY=${MINIO_ROOT_PASSWORD}
+
+# ============================================
+# 应用配置
+# ============================================
+NODE_ENV=production
+APP_PORT=3000
+JWT_SECRET=<生成的32位以上随机字符串>
+JWT_EXPIRES_IN=7d
+```
+
+---
+
+## 数据库迁移
+
+### 首次部署
+```bash
+# 推送 schema 到数据库
+npx prisma db push
+
+# 生成 Prisma Client
+npx prisma generate
+```
+
+### 后续更新（Schema 变更）
+```bash
+# 开发环境：直接推送
+npx prisma db push
+
+# 生产环境：使用迁移（推荐）
+npx prisma migrate deploy
+```
+
+### 回滚（如需）
+```bash
+# 查看迁移历史
+npx prisma migrate status
+
+# 回滚到上一个版本（手动操作数据库）
+# 注意：Prisma 不支持自动回滚，需要手动处理
+```
+
+---
+
+## 服务管理
+
+### 启动/停止服务
+```bash
+# 启动所有服务
+docker-compose -f docker-compose.prod.yml up -d
+
+# 停止所有服务
+docker-compose -f docker-compose.prod.yml down
+
+# 重启单个服务
+docker-compose -f docker-compose.prod.yml restart app
+```
+
+### 查看日志
+```bash
+# 查看所有服务日志
+docker-compose -f docker-compose.prod.yml logs -f
+
+# 查看特定服务日志
+docker-compose -f docker-compose.prod.yml logs -f app
+docker-compose -f docker-compose.prod.yml logs -f postgres
+docker-compose -f docker-compose.prod.yml logs -f redis
+```
+
+### 服务状态
+```bash
+# 查看服务状态
+docker-compose -f docker-compose.prod.yml ps
+
+# 查看资源使用
+docker stats
+```
+
+---
+
+## 备份与恢复
+
+### 数据库备份
+```bash
+# 创建备份
+docker exec furniture3d-postgres pg_dump -U postgres furniture3d > backup_$(date +%Y%m%d).sql
+
+# 恢复备份
+docker exec -i furniture3d-postgres psql -U postgres furniture3d < backup_20240101.sql
+```
+
+### MinIO 文件备份
+```bash
+# 使用 mc 命令行工具
+mc alias set myminio http://localhost:9000 minioadmin minioadmin
+mc mirror myminio/furniture-3d-models ./backup/files/
+```
+
+### 自动备份脚本
+参见 `scripts/backup.sh`
+
+---
+
+## 常见问题
+
+### Q: 数据库连接失败
+```
+Error: Can't reach database server
+```
+**解决**：检查 PostgreSQL 容器是否正常运行，网络是否通畅
+```bash
+docker-compose -f docker-compose.prod.yml ps postgres
+docker-compose -f docker-compose.prod.yml logs postgres
+```
+
+### Q: Redis 连接失败
+```
+Error: Redis connection refused
+```
+**解决**：
+1. 检查 Redis 容器状态
+2. 系统会自动降级为内存缓存，不影响核心功能
+3. 生产环境建议确保 Redis 正常运行
+
+### Q: MinIO 上传失败
+```
+Error: Access Denied
+```
+**解决**：
+1. 检查 MinIO 凭证配置
+2. 确认 Bucket 已创建
+3. 检查 Bucket 权限策略
+
+### Q: 内存不足
+**解决**：使用轻量级模式
+```bash
+docker-compose -f docker-compose.lightweight.yml up -d
+```
+
+---
+
+## 版本更新
+
+### 更新应用
+```bash
+# 拉取最新代码
+git pull
+
+# 重新构建镜像
+docker-compose -f docker-compose.prod.yml build app
+
+# 重启应用
+docker-compose -f docker-compose.prod.yml up -d app
+
+# 执行数据库迁移（如有）
+docker exec -it furniture3d-app npx prisma db push
+```
+
+### 重要提示
+- 更新前请先备份数据库
+- 测试环境验证后再更新生产环境
+- 保留旧版本镜像以便回滚

 ### 11.7 现代化设计元素

 **毛玻璃效果（Glassmorphism）：**
- 使用 `backdrop-blur-sm` 或 `backdrop-blur-md`
+- 使用 `backdrop-blur-xs` 或 `backdrop-blur-md`
 - 半透明背景：`bg-white/60` 或 `bg-slate-800/60`
 - 适用于：导航栏、卡片、模态框

 **微妙渐变：**
- 背景渐变：`bg-gradient-to-br from-slate-50 to-white`
- 按钮渐变（可选）：`bg-gradient-to-r from-indigo-600 to-purple-600`
+- 背景渐变：`bg-linear-to-br from-slate-50 to-white`
+- 按钮渐变（可选）：`bg-linear-to-r from-indigo-600 to-purple-600`
 - 使用原则：非常微妙，不抢夺内容焦点

 **极简阴影：**
- 只使用 `shadow-sm`（轻微阴影）
+- 只使用 `shadow-xs`（轻微阴影）

 ### 5.2 迁移指南

 如果你在代码中看到旧的 CSS 类（如 `text-gray-500`），请替换为语义化的设计令牌类：
-*   ❌ `text-gray-500` -> ✅ `text-[var(--color-label-secondary)]` (或封装好的 Tailwind 类)
-*   ❌ `bg-white` -> ✅ `bg-[var(--color-background-primary)]`
+*   ❌ `text-gray-500` -> ✅ `text-(--color-label-secondary)` (或封装好的 Tailwind 类)
+*   ❌ `bg-white` -> ✅ `bg-(--color-background-primary)`
 *   ❌ `shadow-lg` -> ✅ `shadow-apple-lg`

+# Draco 3D Data Compression
+
+Draco is an open-source library for compressing and decompressing 3D geometric meshes and point clouds. It is intended to improve the storage and transmission of 3D graphics.
+
+[Website](https://google.github.io/draco/) | [GitHub](https://github.com/google/draco)
+
+## Contents
+
+This folder contains three utilities:
+
+* `draco_decoder.js` — Emscripten-compiled decoder, compatible with any modern browser.
+* `draco_decoder.wasm` — WebAssembly decoder, compatible with newer browsers and devices.
+* `draco_wasm_wrapper.js` — JavaScript wrapper for the WASM decoder.
+
+Each file is provided in two variations:
+
+* **Default:** Latest stable builds, tracking the project's [master branch](https://github.com/google/draco).
+* **glTF:** Builds targeted by the [glTF mesh compression extension](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_draco_mesh_compression), tracking the [corresponding Draco branch](https://github.com/google/draco/tree/gltf_2.0_draco_extension).
+
+Either variation may be used with `DRACOLoader`:
+
+```js
+var dracoLoader = new DRACOLoader();
+dracoLoader.setDecoderPath('path/to/decoders/');
+dracoLoader.setDecoderConfig({type: 'js'}); // (Optional) Override detection of WASM support.
+```
+
+Further [documentation on GitHub](https://github.com/google/draco/tree/master/javascript/example#static-loading-javascript-decoder).
