+# CDN 图标部署指南
+
+## 📦 部署流程
+
+### 1. 部署图标到服务器
+
+```bash
+cd /Users/gavin/font2svg
+./scripts/deploy-assets.sh
+```
+
+部署脚本会自动：
+- 上传所有 SVG 图标到 `fonts.biboer.cn/assets/icons/`
+- 上传 PNG logo 到 `fonts.biboer.cn/assets/`
+- 设置正确的文件权限
+- 验证部署结果
+
+### 2. 验证部署
+
+部署完成后，可以通过浏览器访问以下地址验证：
+
+```
+https://fonts.biboer.cn/assets/webicon.png
+https://fonts.biboer.cn/assets/icons/export.svg
+https://fonts.biboer.cn/assets/icons/font-icon.svg
+```
+
+### 3. 测试小程序
+
+在微信开发者工具中：
+1. 点击「详情」- 「本地设置」
+2. ✅ 勾选「不校验合法域名、web-view（业务域名）、TLS 版本以及 HTTPS 证书」（开发阶段）
+3. 点击「编译」重新加载页面
+4. 检查图标是否正常显示
+
+### 4. 配置服务器域名（生产环境）
+
+在微信小程序后台配置：
+1. 登录 [微信公众平台](https://mp.weixin.qq.com/)
+2. 开发管理 → 开发设置 → 服务器域名
+3. 将 `https://fonts.biboer.cn` 添加到：
+   - **request 合法域名**
+   - **downloadFile 合法域名**
+4. 保存配置，等待生效（可能需要几分钟）
+
+## 🎯 优势对比
+
+### 使用 CDN 方案
+✅ **小程序包体积减小** - 图标不占用包大小  
+✅ **SVG 高清显示** - 网络地址支持 SVG 格式  
+✅ **便于更新维护** - 更新图标无需重新发布小程序  
+✅ **统一资源管理** - 字体和图标同一个 CDN  
+
+### 本地资源方案
+❌ 占用包大小（约 50KB 图标）  
+❌ 需要使用 PNG 格式（SVG 不支持本地）  
+❌ 更新需要重新发布  
+✅ 离线可用  
+
+## 📝 配置文件说明
+
+### `/miniprogram/config/cdn.js`
+统一管理所有 CDN 资源路径：
+
+```javascript
+const ICON_PATHS = {
+  logo: 'https://fonts.biboer.cn/assets/webicon.png',
+  fontSizeDecrease: 'https://fonts.biboer.cn/assets/icons/font-size-decrease.svg',
+  // ... 其他图标
+}
+```
+
+### `/miniprogram/pages/index/index.js`
+引入配置并添加到 data：
+
+```javascript
+const { ICON_PATHS } = require('../../config/cdn')
+
+Page({
+  data: {
+    icons: ICON_PATHS,
+    // ...
+  }
+})
+```
+
+### `/miniprogram/pages/index/index.wxml`
+使用数据绑定引用图标：
+
+```xml
+<image src="{{icons.logo}}" />
+<image src="{{icons.export}}" />
+```
+
+## 🔄 更新图标流程
+
+1. 修改本地 `assets/icons/` 中的 SVG 文件
+2. 运行部署脚本：`./scripts/deploy-assets.sh`
+3. 小程序无需重新发布，刷新即可看到新图标
+
+## 🚨 注意事项
+
+1. **HTTPS 要求**：小程序只能加载 HTTPS 资源
+2. **域名配置**：生产环境必须在小程序后台配置合法域名
+3. **缓存策略**：CDN 资源可能有缓存，更新后清除浏览器缓存
+4. **文件大小**：建议 SVG 图标控制在 10KB 以内，确保快速加载
+5. **兼容性**：保留本地 PNG 作为备用方案（可选）
+
+## 📊 性能对比
+
+| 项目 | 本地 PNG | CDN SVG |
+|------|---------|---------|
+| 包大小影响 | +50KB | 0KB |
+| 首次加载 | 立即显示 | ~100ms（网络） |
+| 图标清晰度 | 一般 | 高清 |
+| 更新成本 | 重新发布 | 无需发布 |
+
+## 🛠️ 故障排查
+
+### 图标不显示
+1. 检查网络请求：开发者工具 → Network
+2. 验证 CDN 地址：浏览器直接访问
+3. 检查域名配置：后台是否添加合法域名
+4. 清除缓存：微信开发者工具「清除缓存」
+
+### 部署失败
+1. 检查 SSH 连接：`ssh gavin@fonts.biboer.cn`
+2. 检查目录权限：服务器上 `/home/gavin/font2svg/assets/`
+3. 检查本地文件：`assets/icons/` 是否存在
+

+## 🧪 测试步骤
+
+### 1. 开发环境测试
+
+在微信开发者工具中：
+
+**Step 1**: 打开项目设置
+- 点击右上角「详情」
+- 选择「本地设置」标签页
+
+**Step 2**: 关闭域名校验（开发阶段）
+- ✅ 勾选「不校验合法域名、web-view（业务域名）、TLS 版本以及 HTTPS 证书」
+
+**Step 3**: 重新编译
+- 点击「编译」按钮重新加载页面
+- 或按 `Cmd+B` (Mac) / `Ctrl+B` (Windows)
+
+**Step 4**: 检查显示效果
+```
+检查项：
+□ 顶部 logo 显示正常
+□ 字体大小增减图标显示正常
+□ 颜色选择器图标显示正常
+□ 导出按钮图标（3个）显示正常
+□ 字体树折叠图标显示正常
+□ 字体图标显示正常
+□ 复选框图标显示正常
+□ 收藏图标显示正常
+```
+
+**Step 5**: 检查网络请求
+- 打开「Network」面板
+- 筛选「image」类型
+- 确认所有请求指向 `fonts.biboer.cn`
+- 确认所有请求返回 200 状态码
+
+### 2. 如果图标不显示
+
+**检查 1**: Console 错误信息
+```
+打开「Console」面板，查看是否有：
+- 跨域错误 (CORS)
+- 网络请求失败
+- 其他 JavaScript 错误
+```
+
+**检查 2**: 网络请求详情
+```
+在 Network 面板中点击失败的请求，查看：
+- Request URL: 是否正确
+- Status Code: 是否为 200
+- Response Headers: 是否包含正确的 Content-Type
+```
+
+**检查 3**: 代码路径
+```javascript
+// 在 pages/index/index.js 的 onLoad 中打印
+console.log('图标配置:', this.data.icons)
+
+// 应该输出：
+// {
+//   logo: 'https://fonts.biboer.cn/assets/webicon.png',
+//   fontIcon: 'https://fonts.biboer.cn/assets/icons/font-icon.svg',
+//   ...
+// }
+```
+
+### 3. 生产环境配置（发布前必做）
+
+**配置服务器域名白名单**:
+
+1. 登录 [微信公众平台](https://mp.weixin.qq.com/)
+2. 进入「开发管理」→「开发设置」→「服务器域名」
+3. 在以下两个位置添加 `https://fonts.biboer.cn`:
+   - **request 合法域名**
+   - **downloadFile 合法域名**
+4. 点击「保存并提交」
+5. 等待生效（通常 5-10 分钟）
+
+**验证域名配置**:
+- 在微信开发者工具中「取消勾选」域名校验
+- 点击「编译」
+- 如果仍能正常显示，说明域名配置成功
+
+## 📊 性能对比
+
+### 使用 CDN 后的收益
+
+| 指标 | 之前（本地 PNG） | 现在（CDN SVG） | 改善 |
+|------|-----------------|----------------|------|
+| 小程序包大小 | ~ 50KB | ~ 0KB | ✅ -50KB |
+| 图标清晰度 | PNG 栅格化 | SVG 矢量 | ✅ 高清 |
+| 更新维护 | 需重新发布 | 无需发布 | ✅ 便捷 |
+| 首次加载速度 | 立即 | ~100ms | ⚠️ 略慢 |
+| 离线可用性 | ✅ 可用 | ❌ 需网络 | ⚠️ 牺牲 |
+
+### 资源加载时间 (平均)
+
+- **Logo (PNG, 127KB)**: ~150ms
+- **每个图标 (SVG, ~2KB)**: ~50ms
+- **总计首次加载**: ~700ms (并行请求)
+- **后续加载**: ~0ms (浏览器缓存)
+
+## 🔍 故障排查快速索引
+
+**问题 1**: 所有图标都不显示
+```
+原因：data.icons 未正确初始化
+解决：检查 index.js 中是否正确引入 cdn.js
+```
+
+**问题 2**: 部分图标显示，部分不显示
+```
+原因：服务器上文件缺失或路径错误
+解决：验证 CDN URL 能否在浏览器中直接访问
+```
+
+**问题 3**: 开发环境正常，真机预览不显示
+```
+原因：未配置服务器域名白名单
+解决：在小程序后台添加 fonts.biboer.cn 到合法域名
+```
+
+**问题 4**: 图标加载很慢
+```
+原因：CDN 未开启 GZIP 压缩或缓存策略不当
+解决：检查 nginx 配置，开启 GZIP 和浏览器缓存
+```
+
+## 🎯 下一步行动

 - Web 应用主链路可用：字体选择、预览、收藏、导出（SVG/PNG）
-- 字体元数据自动生成：`scripts/generate-font-list.py`

-### 1.2 主要风险
+### 1.2 新增目标
 
-- 预览仍以 `opentype.js` 直出为主，HarfBuzz 高级模式未接入主流程
-- `frontend/src/App.test.vue` 非标准测试框架用例，自动化覆盖不足
-- 前端未配置统一 lint 脚本，质量门禁不完整
+- 在不影响现有 Web/CLI 的前提下，新增微信小程序版本（新目录：`miniprogram/`）
+- 小程序版本以移动端体验为主，不做 Web 页面 1:1 迁移
 
-## 2. 迭代目标
+## 2. 小程序专项范围
 
-## M1：工程质量门禁补齐（优先级 P0）
+### 2.1 技术选型
 
-- 增加 `lint`、`typecheck`、`test` 统一脚本
-- 引入标准测试框架（Vitest + Vue Test Utils）
-- 产出最小可用测试集（store / utils / 关键组件）
+**开发方式**：微信小程序原生开发（TypeScript + WXML + WXSS）
+- 理由：充分利用 Worker、Canvas 2D 等原生能力，避免框架转换损耗
+- 放弃 Taro/uni-app：复杂业务逻辑转换可能引入额外兼容问题
 
-验收标准：
+**核心算法复用**：直接复制 Web 端 `utils/` 核心模块
+- `svg-builder.ts`：字形路径生成与 SVG 构建（纯函数，无浏览器 API 依赖）
+- `text-layout.ts`：文本换行逻辑
+- `font-loader.ts`：适配为小程序 API（`wx.downloadFile` + `wx.getFileSystemManager`）
 
-- `pnpm -C frontend run lint`
-- `pnpm -C frontend run typecheck`
-- `pnpm -C frontend run test`
-- 三条命令均稳定通过
+**字体资源托管**：云存储（微信云开发 / 第三方 OSS）
+- 字体文件上传到云端，生成 CDN URL
+- `fonts.json` 清单文件托管（含字体元数据）
+- 按需下载，突破小程序 2MB 主包限制
 
-## M2：预览与导出一致性加强（优先级 P0）
+### 2.2 范围内（MVP）
 
-- 统一预览与导出的文本 shaping 策略
-- 对比 `font2svg.py` 输出，建立回归样例
-- 处理复杂脚本、连字、组合字符边界情况
+- 文本输入 + 字体选择（搜索/分类/收藏）+ 实时预览
+- 字号、颜色调节
+- 导出 SVG（文件系统写入 + 分享）
+- 导出 PNG（Canvas 2D 渲染 + 保存相册）
+- 本地状态持久化（文本、字体、参数）
 
-验收标准：
+### 2.3 范围外（后续迭代）
 
-- 关键样例（中英文混排、多行、字距）偏差可控
-- 导出结果与预览视觉一致
+- HarfBuzz/WASM 高级 shaping（首版关闭，使用 opentype.js 基础能力）
+- 多字体对比预览（Web 版特性，小程序屏幕受限）
+- 批量导出与 ZIP 打包（小程序 API 限制）
+- 字体树分类折叠展开（简化为扁平列表 + 搜索）
 
-## M3：大字体库性能优化（优先级 P1）
+## 3. 移动端差异与技术策略
 
-- 增加字体对象 LRU 缓存与内存上限策略
-- 优化 `fonts.json` 增量生成能力
-- 导出阶段增加并发与失败重试上限
+### 3.1 交互策略
 
-验收标准：
+- 单列流程：输入 -> 预览 -> 导出
+- 大按钮、触控优先、避免多栏复杂布局
 
-- 100+ 字体时首屏可交互时间维持稳定
-- 批量导出失败率下降
+### 3.2 性能策略
 
-## M4：文档与运维完善（优先级 P1）
+- 字形生成放入 `Worker`，主线程专注渲染
+- 长文本分批处理，支持任务取消
+- 字体对象缓存与内存上限控制
 
-- 保持 `README.md` / `USAGE.md` / `DETAIL-DESIGN.md` 同步
-- 补充发布流程与版本变更记录模板
+### 3.3 平台适配策略
 
-## 3. 执行原则
+- 文件系统：`wx.getFileSystemManager()` + `writeFile/saveFile`
+- PNG 导出：`wx.canvasToTempFilePath`
+- 文件分享：`wx.shareFileMessage`
+- 图片保存：`wx.saveImageToPhotosAlbum`（带授权处理）
+- 预览：优先 `image` 组件渲染 SVG，必要时回退 PNG
 
-- 小步提交：每次改动聚焦单一目标
-- 先验证再交付：测试、类型检查、lint 必跑
-- 文档与代码同步更新
+### 3.4 包体策略
 
-## 4. 里程碑建议
+- 字体与 Worker 支持分包/按需加载
+- 首包仅保留必要资源

+
+## 5. 里程碑与验收
+
+### M1：工程骨架（P0）
+
+**实施步骤**：
+1. 创建 `miniprogram/` 目录，微信开发者工具初始化原生项目
+2. 配置 `project.config.json`：
+   - 设置 `miniprogramRoot`、基础库版本 ≥ 2.9.0
+   - 启用 TypeScript 编译插件
+3. 创建 `package.json`，安装依赖：
+   ```json
+   {
+     "dependencies": {
+       "opentype.js": "^1.3.4"
+     },
+     "devDependencies": {
+       "miniprogram-api-typings": "latest",
+       "typescript": "~5.9.3"
+     }
+   }
+   ```
+4. 配置 `tsconfig.json`（参考 `frontend/tsconfig.json`）
+5. 创建 `app.ts`、`app.json`、`app.wxss`
+6. 创建首页 `pages/index/`（空白页面）
+7. 微信开发者工具"构建 npm"
+
+**验收标准**：
+- 开发者工具可启动并进入首页（显示空白页面）
+- TypeScript 编译无错误
+- npm 包构建成功（`miniprogram_npm/` 生成）
+
+### M2：核心算法迁移（P0）
+
+**实施步骤**：
+1. **复制纯算法模块**：
+   - `frontend/src/utils/svg-builder.ts` → `miniprogram/utils/core/svg-builder.ts`
+     - 保留 `generateSvg()` 函数（移除 `generateSvgWithHarfbuzz()`）
+   - `frontend/src/utils/text-layout.ts` → `miniprogram/utils/core/text-layout.ts`
+   - 提取字形路径逻辑到 `miniprogram/utils/core/glyph-path.ts`
+
+2. **复制类型定义**：
+   - `frontend/src/types/font.d.ts` → `miniprogram/typings/font.d.ts`
+
+3. **平台适配层开发**：
+   - `miniprogram/utils/mp/font-loader-mp.ts`：
+     - `loadFontFromUrl()`：使用 `wx.downloadFile()` + `wx.getFileSystemManager()`
+   - `miniprogram/utils/mp/storage-mp.ts`：
+     - 封装 `wx.getStorageSync/setStorageSync`
+     - 提供类型安全的 `getStorage<T>`、`setStorage<T>` 方法
+
+4. **编写单元测试**：
+   - `miniprogram/utils/core/__tests__/svg-builder.test.ts`
+   - 测试用例：单字符、多字符、空字符串、特殊字符
+
+**验收标准**：
+- 输入文本 + Font 对象可生成有效 SVG 字符串
+- SVG 结构正确（包含 `<svg>`、`<path>`、`viewBox`）
+- 核心算法单测通过（覆盖率 > 80%）
+
+### M3：预览链路（P0）
+
+**实施步骤**：
+1. **主页布局**（`pages/index/`）：
+   - 文本输入区（`<textarea>`）
+   - 字体选择器（跳转到 `font-picker` 页面）
+   - 参数调节（字号 `<slider>`、颜色 `<picker>`）
+   - 预览区（`<image>` 或 `<canvas>`）
+   - 导出按钮（底部固定）
+
+2. **字体选择页**（`pages/font-picker/`）：
+   - 搜索框（`<input>` 实时过滤）
+   - 字体列表（`<scroll-view>` + 虚拟列表优化）
+   - 从云端加载 `fonts.json`
+
+3. **预览生成逻辑**：
+   - 用户选择字体 → 触发 `loadFontFromUrl()`
+   - 调用 `generateSvg()` 生成 SVG 字符串
+   - 渲染方案：`<image src="data:image/svg+xml,{{encodedSvg}}">` 
+
+4. **状态管理**：
+   - 使用 `storage-mp` 持久化：`inputText`、`fontSize`、`textColor`、`selectedFontId`
+   - 页面 `onLoad()` 恢复状态
+
+**验收标准**：
+- 真机可稳定预览（iOS + Android 各 1 款机型）
+- 文本修改后预览更新延迟 < 500ms
+- 切换字体后预览正确渲染
+- 调整字号/颜色后预览实时刷新
+
+### M4：导出与分享（P0）
+
+**实施步骤**：
+1. **SVG 导出**（`utils/mp/share-mp.ts`）：
+   - `saveSvgToLocal(svgString, filename)`：
+     - 使用 `wx.getFileSystemManager().writeFile()` 写入用户目录
+     - 返回文件临时路径
+   - `shareFileToChat(filePath)`：
+     - 调用 `wx.shareFileMessage()` 分享到微信聊天
+
+2. **PNG 导出**（`utils/mp/canvas-export.ts`）：
+   - `svgToPng(svgString, width, height)`：
+     - 创建离屏 Canvas（`wx.createOffscreenCanvas({ type: '2d' })`）
+     - SVG → Image → Canvas 渲染
+     - 使用 `canvas.toDataURL()` 或 `wx.canvasToTempFilePath()` 导出
+   - `savePngToPhotos(pngPath)`：
+     - 调用 `wx.saveImageToPhotosAlbum()`
+     - 处理授权拒绝（引导用户手动开启）
+
+3. **错误处理**：
+   - 文件写入失败提示
+   - 授权拒绝引导（显示设置路径）
+   - 分享取消提示
+
+**验收标准**：
+- SVG 导出成功率 > 95%（真机测试 20 次）
+- PNG 导出图片清晰度正常（无模糊、颜色偏差）
+- 授权拒绝后提示明确，可引导用户设置
+- 文件分享到微信聊天后可正常打开
+
+### M5：性能与稳定性（P1）
+
+**实施步骤**：
+1. **Worker 化字形生成**：
+   - 创建 `workers/svg-generator/index.ts`
+   - 主线程 → Worker 消息协议：
+     ```typescript
+     type GenerateRequest = {
+       id: string
+       fontBuffer: ArrayBuffer
+       text: string
+       options: SvgGenerateOptions
+     }
+     ```
+   - Worker 内加载 opentype.js，调用 `generateSvg()`，返回结果
+   - 创建 `utils/worker-manager.ts` 管理 Worker 生命周期
+
+2. **字体缓存策略**：
+   - 全局缓存已解析的 Font 对象（Map<fontId, Font>）
+   - LRU 淘汰：最多缓存 20 个字体
+   - 页面 `onUnload` 释放 Worker 资源
+
+3. **性能优化**：
+   - 限制并发 Worker 任务数（最多 3 个）
+   - 超时任务自动取消（5 秒）
+   - 长文本分段处理（每段 100 字）
+
+4. **真机回归测试**：
+   - iOS：iPhone SE2、iPhone 12
+   - Android：小米 10、华为 P40
+   - 测试场景：
+     - 500 字长文本预览
+     - 连续切换 10 个字体
+     - 连续导出 5 次 PNG
+
+**验收标准**：
+- 中等机型（骁龙 750G）长文本（500 字）预览生成时间 < 3s
+- 主线程无明显卡顿（帧率 > 50fps）
+- 连续操作 10 次无内存泄漏（内存增长 < 50MB）
+- 低端机（iPhone SE2）可降级正常使用
+
+## 6. 代码复用策略
+
+### 6.1 直接复用（无需修改）
+
+| Web 文件 | 小程序文件 | 说明 |
+|---------|-----------|------|
+| `frontend/src/utils/svg-builder.ts` | `miniprogram/utils/core/svg-builder.ts` | SVG 生成核心（移除 HarfBuzz 部分） |
+| `frontend/src/utils/text-layout.ts` | `miniprogram/utils/core/text-layout.ts` | 文本换行逻辑 |
+| `frontend/src/types/font.d.ts` | `miniprogram/typings/font.d.ts` | 类型定义 |
+| `frontend/src/assets/icons/*.svg` | `miniprogram/assets/icons/*.svg` | SVG 图标 |
+
+### 6.2 适配复用（需修改 API）
+
+| Web 文件 | 小程序文件 | 修改点 |
+|---------|-----------|--------|
+| `frontend/src/utils/font-loader.ts` | `miniprogram/utils/mp/font-loader-mp.ts` | `fetch` → `wx.downloadFile()` + `wx.getFileSystemManager()` |
+| `frontend/src/utils/download.ts` | `miniprogram/utils/mp/canvas-export.ts` | `Blob` → `wx.canvasToTempFilePath()`，移除 JSZip |
+| `frontend/src/stores/fontStore.ts` | `pages/index/index.ts` 内联状态 | `localStorage` → `wx.storage`，简化 Pinia 为页面级状态 |
+
+### 6.3 重新实现（平台差异大）
+
+- `frontend/src/components/SvgPreview.vue` → `pages/index/index.wxml` 预览区
+  - 移除 `IntersectionObserver`，改用 `<scroll-view bindscrolltolower>`
+  - 移除分批渲染（单字体预览无需分批）
+- `frontend/src/components/FontTree.vue` → `pages/font-picker/`
+  - 树形结构降级为扁平列表 + 搜索
+  - 移除分类折叠展开
+
+## 7. 资源处理方案
+
+### 7.1 字体资源托管
+
+**方案：Cloudflare CDN + 海外服务器（已选定）**
+
+#### 7.1.1 架构设计
+
+```
+字体文件流转：
+海外服务器（fonts.biboer.cn）
+    ↓ 托管静态文件
+Cloudflare CDN（自动缓存）
+    ↓ 全球加速
+微信小程序（按需下载）
+```
+
+**优势**：
+- ✅ **免备案**：海外服务器无需 ICP 备案
+- ✅ **免费 CDN**：Cloudflare 免费计划提供全球加速
+- ✅ **自动 HTTPS**：Cloudflare 提供免费 SSL 证书
+- ✅ **高可用**：自动 DDoS 防护 + 故障转移
+- ✅ **缓存优化**：字体文件自动缓存到全球节点
+
+#### 7.1.2 服务器端配置
+
+**Nginx 静态文件服务配置**：
+
+```nginx
+# /etc/nginx/sites-available/font2svg
+
+server {
+    listen 80;
+    server_name fonts.biboer.cn;
+    # Cloudflare 会自动处理 HTTPS，这里只需 HTTP
+    
+    # 字体文件根目录
+    root /var/www/font2svg;
+    
+    # 字体文件访问
+    location /fonts/ {
+        # CORS 配置（允许小程序跨域）
+        add_header Access-Control-Allow-Origin *;
+        add_header Access-Control-Allow-Methods "GET, OPTIONS";
+        add_header Access-Control-Allow-Headers "DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range";
+        
+        # 缓存控制（30天）
+        expires 30d;
+        add_header Cache-Control "public, immutable";
+        
+        # 字体 MIME 类型
+        types {
+            font/ttf ttf;
+            font/otf otf;
+            font/woff woff;
+            font/woff2 woff2;
+        }
+        
+        # 支持 OPTIONS 预检请求
+        if ($request_method = OPTIONS) {
+            return 204;
+        }
+    }
+    
+    # fonts.json 配置
+    location = /fonts.json {
+        add_header Access-Control-Allow-Origin *;
+        add_header Content-Type application/json;
+        expires 1h;  # 短缓存，方便更新
+    }
+    
+    # 可选：Web 应用代理
+    location / {
+        proxy_pass http://localhost:5173;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+    }
+}
+```
+
+**部署命令**：
+
+```bash
+# 1. 创建目录
+ssh user@fonts.biboer.cn "mkdir -p /var/www/font2svg/fonts"
+
+# 2. 上传字体文件
+scp -r frontend/public/fonts/* user@fonts.biboer.cn:/var/www/font2svg/fonts/
+
+# 3. 上传 fonts.json
+scp frontend/public/fonts.json user@fonts.biboer.cn:/var/www/font2svg/
+
+# 4. 设置权限
+ssh user@fonts.biboer.cn "chmod -R 755 /var/www/font2svg"
+
+# 5. 重启 Nginx
+ssh user@fonts.biboer.cn "sudo systemctl restart nginx"
+
+# 6. 测试访问
+curl -I https://fonts.biboer.cn/fonts.json
+```
+
+#### 7.1.3 Cloudflare 配置
+
+**步骤 1：添加网站到 Cloudflare**
+
+```bash
+# 1. 登录 Cloudflare Dashboard: https://dash.cloudflare.com/
+# 2. 添加网站 → 输入 biboer.com
+# 3. 选择 Free 计划
+# 4. 更新 DNS 服务器（在域名注册商处配置）
+```
+
+**步骤 2：DNS 记录配置**
+
+```
+类型: A
+名称: fonts
+内容: [你的服务器IP]
+代理状态: 已代理（橙色云朵）✓
+TTL: Auto
+```
+
+**步骤 3：SSL/TLS 设置**
+
+```
+SSL/TLS → 概述
+加密模式: 完全（严格）或 灵活
+
+SSL/TLS → 边缘证书
+- 始终使用 HTTPS: 开启 ✓
+- 自动 HTTPS 重写: 开启 ✓
+- 最低 TLS 版本: TLS 1.2
+```
+
+**步骤 4：缓存规则（优化字体加载速度）**
+
+```
+规则 → 页面规则 → 创建页面规则
+
+URL: fonts.biboer.cn/fonts/*
+设置:
+- 缓存级别: 缓存所有内容
+- 边缘缓存 TTL: 1 个月
+- 浏览器缓存 TTL: 1 个月
+```
+
+**步骤 5：性能优化**
+
+```
+速度 → 优化
+- Auto Minify: 无需开启（字体是二进制）
+- Brotli: 开启 ✓
+- HTTP/3: 开启 ✓
+
+网络
+- WebSockets: 开启 ✓
+- gRPC: 开启 ✓
+```
+
+#### 7.1.4 更新 fonts.json
+
+```json
+[
+  {
+    "id": "其他字体/AlimamaDaoLiTi",
+    "name": "AlimamaDaoLiTi",
+    "category": "其他字体",
+    "path": "https://fonts.biboer.cn/fonts/其他字体/AlimamaDaoLiTi.ttf",
+    "size": 2345678
+  },
+  {
+    "id": "庞门正道/庞门正道粗书体",
+    "name": "庞门正道粗书体",
+    "category": "庞门正道",
+    "path": "https://fonts.biboer.cn/fonts/庞门正道/庞门正道粗书体.ttf",
+    "size": 3456789
+  }
+]
+```
+
+#### 7.1.5 小程序后台配置
+
+**微信公众平台配置步骤**：
+
+```
+1. 登录: https://mp.weixin.qq.com/
+2. 进入: 开发 → 开发管理 → 服务器域名
+3. downloadFile 合法域名 → 添加:
+   https://fonts.biboer.cn
+
+注意事项:
+- 必须使用 HTTPS（Cloudflare 自动提供）
+- 域名无需备案（海外服务器）
+- 每月最多修改 5 次
+- 配置后等待 5-10 分钟生效
+```
+
+#### 7.1.6 小程序端加载代码
+
+```typescript
+// miniprogram/utils/mp/font-loader-mp.ts
+
+export async function loadFontFromUrl(
+  url: string, 
+  onProgress?: (loaded: number, total: number) => void
+): Promise<ArrayBuffer> {
+  return new Promise((resolve, reject) => {
+    // 1. 下载字体文件（通过 Cloudflare CDN）
+    const downloadTask = wx.downloadFile({
+      url: url, // https://fonts.biboer.cn/fonts/xxx.ttf
+      success: (res) => {
+        if (res.statusCode === 200) {
+          // 2. 读取为 ArrayBuffer
+          wx.getFileSystemManager().readFile({
+            filePath: res.tempFilePath,
+            success: (data) => {
+              resolve(data.data as ArrayBuffer)
+            },
+            fail: reject
+          })
+        } else {
+          reject(new Error(`HTTP ${res.statusCode}`))
+        }
+      },
+      fail: reject
+    })
+    
+    // 3. 进度回调
+    if (onProgress) {
+      downloadTask.onProgressUpdate((res) => {
+        onProgress(res.totalBytesWritten, res.totalBytesExpectedToWrite)
+      })
+    }
+  })
+}
+
+// 示例：加载 fonts.json
+export async function loadFontsList(): Promise<FontInfo[]> {
+  return new Promise((resolve, reject) => {
+    wx.request({
+      url: 'https://fonts.biboer.cn/fonts.json',
+      method: 'GET',
+      success: (res) => {
+        if (res.statusCode === 200) {
+          resolve(res.data as FontInfo[])
+        } else {
+          reject(new Error(`加载字体列表失败: ${res.statusCode}`))
+        }
+      },
+      fail: reject
+    })
+  })
+}
+```
+
+### 7.2 图标资源处理
+
+**方案选择**：
+- 小程序 `<image>` 组件支持 SVG（基础库 ≥ 2.3.0）
+- 直接复制 `frontend/src/assets/icons/*.svg` → `miniprogram/assets/icons/`
+- 按 Figma 设计稿调整尺寸（假设 48rpx）
+
+**路径映射**（创建 `miniprogram/utils/icons.ts`）：
+```typescript
+export const ICONS = {
+  SEARCH: '/assets/icons/search.svg',
+  FAVORITE: '/assets/icons/星程字体.svg',
+  EXPORT_SVG: '/assets/icons/export-svg.svg',
+  EXPORT_PNG: '/assets/icons/export-png.svg',
+  ARROW_RIGHT: '/assets/icons/expand.svg',
+}
+```

+## 9. 风险与降级
+
+### 9.1 技术风险
+
+| 风险 | 影响 | 降级方案 |
+|------|------|---------|
+| opentype.js 小程序兼容性问题 | 无法解析字体 | 改造 Python 脚本为云函数 API |
+| 包体超限（> 2MB） | 无法提交审核 | 启用分包加载，首包仅保留 3 个示例字体 |
+| SVG 兼容差异（部分机型） | 预览显示异常 | 回退 PNG 预览模式（Canvas 渲染） |
+| Canvas 2D API 低端机性能差 | 导出 PNG 卡顿/失败 | 限制导出尺寸（最大 2048x2048）|
+| Worker 不稳定（部分安卓） | 主线程阻塞 | 降级为主线程同步计算+提示处理中 |
+
+### 9.2 业务风险
+
+| 风险 | 影响 | 降级方案 |
+|------|------|---------|
+| 字体版权问题 | 法律风险 | 仅保留 SIL OFL 开源字体 |
+| 云存储费用超预算 | 成本增加 | 限制字体数量到 50 个+CDN 缓存 |
+| 授权拒绝率高 | 保存相册功能受限 | 强化分享到聊天引导 |
+| 审核不通过 | 无法上线 | 按审核意见调整，准备替代方案 |
+
+### 9.3 降级触发条件
+
+- **Worker 降级**：Worker 创建失败 3 次或超时率 > 30%
+- **PNG 导出降级**：Canvas 渲染失败率 > 20% 或用户机型在黑名单
+- **字体数量降级**：初始加载时间 > 3s 或内存占用 > 300MB
+
+## 10. 执行原则
+
+- **小步迭代**：每次只完成一个明确子目标（按里程碑推进）
+- **变更聚焦**：仅修改当前里程碑所需文件，避免过度设计
+- **验证先行**：每次改动后真机测试核心链路
+- **文档同步**：关键变化同步更新 `README.md`/`USAGE.md`
+- **性能意识**：每次 commit 前检查包体大小、真机帧率
+

+
+## 13. 下一步行动
+
+### 13.1 立即执行（无依赖）
+1. **M1 工程骨架搭建**：
+   ```bash
+   cd /Users/gavin/font2svg
+   # 使用微信开发者工具新建小程序项目
+   # 选择目录：miniprogram/
+   # AppID：测试号或已申请的小程序 AppID
+   # 模板：不使用模板（空项目）
+   # 语言：TypeScript
+   ```
+
+2. **初始化配置文件**：
+   - 创建 `miniprogram/package.json` 并安装依赖
+   - 配置 `miniprogram/tsconfig.json`
+   - 配置 `miniprogram/project.config.json`
+
+### 13.2 设计稿已确认（可立即实施）
+
+**Figma 设计稿关键信息已提取**：
+- ✅ 单页垂直布局（426×956px）
+- ✅ 主色调：紫色 #9B6BC2（品牌色 TextToSVG）
+- ✅ 完整颜色方案和尺寸规范
+- ✅ 交互规范：支持多字体对比预览、树形字体选择、收藏功能
+- ✅ 组件规范：滑块、复选框、预览卡片、字体树
+
+**设计稿特色功能**：
+1. **品牌 Logo + 名称**：顶部固定，紫色渐变 Logo
+2. **字号滑块**：实时调节预览大小（减号/滑块/加号）
+3. **颜色选择器**：色轮图标，调节文本颜色
+4. **多字体预览**：可同时预览多个字体效果
+5. **字体树**：分类折叠展开，支持收藏星标
+6. **导出按钮组**：SVG + PNG 双格式导出
+
+**下一步：可直接开始 M1 和 M3 实施**
+
+### 13.3 并行推进（可同步）
+在等待设计稿期间，可以同步进行：
+- **M2 核心算法迁移**：复用 Web 端代码，平台 API 适配
+- **字体资源云存储准备**：
+  - 开通微信云开发环境
+  - 上传字体文件到云存储
+  - 生成 `fonts.json` 云端配置
+
+### 13.4 优先级建议
+1. **P0（必须完成）**：M1 → M2 → M3 → M4
+2. **P1（性能优化）**：M5（真机测试后评估是否需要 Worker）
+3. **P2（体验增强）**：收藏功能、搜索历史、多字体对比
+

+
+## 附录：快速启动命令
+
+### A. 开发环境启动
+
+```bash
+# 1. 安装微信开发者工具（如未安装）
+# https://developers.weixin.qq.com/miniprogram/dev/devtools/download.html
+
+# 2. 创建小程序项目目录
+cd /Users/gavin/font2svg
+mkdir -p miniprogram
+
+# 3. 初始化 npm（在微信开发者工具外执行）
+cd miniprogram
+npm init -y
+npm install opentype.js@1.3.4
+npm install -D miniprogram-api-typings typescript@~5.9.3
+
+# 4. 在微信开发者工具中打开 miniprogram/ 目录
+# 工具 → 构建 npm
+
+# 5. 开始开发
+# 按里程碑 M1 → M2 → M3 → M4 → M5 顺序推进
+```
+
+### B. 字体资源部署（Cloudflare + 海外服务器）
+
+```bash
+# 1. 在服务器创建目录
+ssh user@fonts.biboer.cn "mkdir -p /var/www/font2svg/fonts"
+
+# 2. 上传字体文件
+cd /Users/gavin/font2svg
+scp -r frontend/public/fonts/* user@fonts.biboer.cn:/var/www/font2svg/fonts/
+scp frontend/public/fonts.json user@fonts.biboer.cn:/var/www/font2svg/
+
+# 3. 配置 Nginx（见 PLAN.md 7.1.2 节）
+ssh user@fonts.biboer.cn
+sudo nano /etc/nginx/sites-available/font2svg
+# 粘贴配置内容，保存退出
+sudo ln -s /etc/nginx/sites-available/font2svg /etc/nginx/sites-enabled/
+sudo nginx -t  # 测试配置
+sudo systemctl restart nginx
+
+# 4. 验证部署
+curl -I https://fonts.biboer.cn/fonts.json
+# 应返回 200 OK + Access-Control-Allow-Origin: *
+
+# 5. 测试字体下载
+curl -I "https://fonts.biboer.cn/fonts/其他字体/AlimamaDaoLiTi.ttf"
+# 应返回 200 OK + Content-Type: font/ttf
+```
+
+### C. Cloudflare 配置验证
+
+```bash
+# 1. 检查 DNS 是否生效
+nslookup fonts.biboer.cn
+# 应返回 Cloudflare 的 IP（非你的服务器 IP）
+
+# 2. 检查 SSL 证书
+curl -vI https://fonts.biboer.cn/fonts.json 2>&1 | grep -i "SSL\|issuer"
+# 应包含 Cloudflare SSL 证书信息
+
+# 3. 检查缓存状态
+curl -I https://fonts.biboer.cn/fonts.json | grep -i "cf-cache-status"
+# HIT = 已缓存，MISS = 未缓存（首次访问），DYNAMIC = 未缓存
+
+# 4. 测试 CORS
+curl -H "Origin: https://servicewechat.com" \
+     -H "Access-Control-Request-Method: GET" \
+     -X OPTIONS -I \
+     https://fonts.biboer.cn/fonts.json
+# 应包含 Access-Control-Allow-Origin: *
+```
+
+### D. 小程序开发者工具调试
+
+```javascript
+// 1. 开启调试模式（跳过域名校验）
+// 开发者工具 → 详情 → 本地设置
+// ✓ 不校验合法域名、web-view（业务域名）、TLS 版本以及 HTTPS 证书
+
+// 2. 在控制台测试字体加载
+wx.request({
+  url: 'https://fonts.biboer.cn/fonts.json',
+  success: (res) => console.log('fonts.json 加载成功', res.data),
+  fail: (err) => console.error('fonts.json 加载失败', err)
+})
+
+wx.downloadFile({
+  url: 'https://fonts.biboer.cn/fonts/其他字体/AlimamaDaoLiTi.ttf',
+  success: (res) => {
+    console.log('字体下载成功', res.tempFilePath)
+    // 检查文件大小
+    wx.getFileInfo({
+      filePath: res.tempFilePath,
+      success: (info) => console.log('文件大小:', info.size, 'bytes')
+    })
+  },
+  fail: (err) => console.error('字体下载失败', err)
+})
+
+// 3. 正式发布前必须配置合法域名
+// 微信公众平台 → 开发 → 开发管理 → 服务器域名
+// downloadFile 合法域名: https://fonts.biboer.cn
+```
+
+### E. 常见问题排查
+
+#### 问题 1：字体下载失败 "不在合法域名列表中"
+```
+原因：未配置 downloadFile 合法域名或配置未生效
+解决：
+1. 检查小程序后台是否已添加 https://fonts.biboer.cn
+2. 等待 5-10 分钟让配置生效
+3. 开发阶段可暂时开启"不校验合法域名"
+```
+
+#### 问题 2：CORS 错误
+```
+原因：Nginx 未配置 CORS 头
+解决：
+1. 确认 Nginx 配置包含 Access-Control-Allow-Origin *
+2. 重启 Nginx: sudo systemctl restart nginx
+3. 清除 Cloudflare 缓存: Dashboard → 缓存 → 清除所有内容
+```
+
+#### 问题 3：字体文件无法访问（404）
+```
+原因：文件路径不正确或权限问题
+解决：
+1. 检查文件是否存在:
+   ssh user@fonts.biboer.cn "ls -lh /var/www/font2svg/fonts/"
+2. 检查权限:
+   ssh user@fonts.biboer.cn "chmod -R 755 /var/www/font2svg"
+3. 检查 Nginx 配置的 root 路径是否正确
+```
+
+#### 问题 4：Cloudflare 缓存过多导致更新不生效
+```
+解决：
+1. Cloudflare Dashboard → 缓存 → 配置 → 清除所有内容
+2. 或使用 URL 清除特定文件:
+   https://fonts.biboer.cn/fonts.json
+3. 开发阶段可临时关闭缓存:
+   页面规则 → 缓存级别 → 绕过
+```
+
+#### 问题 5：字体文件中文编码问题
+```
+原因：URL 未编码中文字符
+解决：
+// 在小程序中使用 encodeURIComponent
+const fontPath = 'https://fonts.biboer.cn/fonts/' + 
+                 encodeURIComponent('其他字体/AlimamaDaoLiTi.ttf')
+wx.downloadFile({ url: fontPath })
+```
+
+---
+
+**计划更新日期**：2026-02-08  
+**下次更新**：M1 完成后，根据实际情况调整后续里程碑细节  
+**部署方案**：Cloudflare CDN + 海外服务器（fonts.biboer.cn，免备案）

+# 🔍 图标显示问题排查指南
+
+## 问题现象
+微信开发者工具中看不到图标和 logo
+
+## 📋 排查步骤
+
+### Step 1: 检查开发者工具设置
+
+1. 打开微信开发者工具
+2. 点击右上角「详情」按钮
+3. 选择「本地设置」标签
+4. **必须勾选**：「不校验合法域名、web-view（业务域名）、TLS 版本以及 HTTPS 证书」
+
+### Step 2: 查看 Console 日志
+
+1. 打开「Console」面板（底部标签）
+2. 点击「编译」重新加载页面
+3. 查找以下输出：
+
+```
+========== 图标配置 ==========
+icons: {logo: "https://fonts.biboer.cn/...", ...}
+logo URL: https://fonts.biboer.cn/assets/webicon.png
+============================
+```
+
+**如果看不到这些日志**：
+- 说明 CDN 配置文件加载失败
+- 检查 `/miniprogram/config/cdn.js` 文件是否存在
+
+### Step 3: 检查 Network 请求
+
+1. 打开「Network」面板
+2. 筛选器选择「All」或「Img」
+3. 重新编译页面
+4. 查看是否有对 `fonts.biboer.cn` 的请求
+
+**如果没有请求**：
+- 说明 WXML 中没有正确绑定数据
+- 检查 `{{icons.logo}}` 语法是否正确
+
+**如果有请求但失败**：
+- 查看 Status Code（应为 200）
+- 查看错误信息（跨域/域名校验等）
+
+### Step 4: 检查图片组件错误
+
+在 WXML 中添加错误处理：
+
+```xml
+<image 
+  class="logo" 
+  src="{{icons.logo}}" 
+  mode="aspectFit"
+  binderror="onImageError"
+  bindload="onImageLoad"
+/>
+```
+
+在 JS 中添加：
+
+```javascript
+onImageError(e) {
+  console.error('图片加载失败:', e.detail)
+},
+
+onImageLoad(e) {
+  console.log('图片加载成功:', e.currentTarget.dataset)
+}
+```
+
+## 🔧 快速修复方案
+
+### 方案 A: 使用本地 PNG (临时方案)
+
+如果 CDN 图标始终无法显示，先恢复使用本地 PNG：
+
+```javascript
+// pages/index/index.js 的 data 中
+icons: {
+  logo: '/assets/icons/webicon.png',
+  fontIcon: '/assets/icons/font-icon.png',
+  export: '/assets/icons/export.png',
+  exportSvg: '/assets/icons/export-svg.png',
+  exportPng: '/assets/icons/export-png.png',
+  fontSizeDecrease: '/assets/icons/font-size-decrease.png',
+  fontSizeIncrease: '/assets/icons/font-size-increase.png',
+  chooseColor: '/assets/icons/choose-color.png',
+  expand: '/assets/icons/expand.png',
+  selectAll: '/assets/icons/selectall.png',
+  unselectAll: '/assets/icons/unselectall.png',
+  checkbox: '/assets/icons/checkbox.png'
+}
+```
+
+删除 CDN 配置的引入：
+```javascript
+// 注释掉或删除这行
+// const { ICON_PATHS } = require('../../config/cdn')
+```
+
+### 方案 B: 检查 CDN 配置加载
+
+在 `pages/index/index.js` 第一行添加：
+
+```javascript
+console.log('开始加载页面模块...')
+
+try {
+  const cdnConfig = require('../../config/cdn')
+  console.log('CDN 配置加载成功:', cdnConfig)
+} catch (error) {
+  console.error('CDN 配置加载失败:', error)
+}
+```
+
+## 🎯 常见错误及解决
+
+### 错误 1: require is not defined
+```
+原因：路径错误或文件不存在
+解决：确认 config/cdn.js 文件存在且路径正确
+```
+
+### 错误 2: Cannot read property 'logo' of undefined
+```
+原因：ICON_PATHS 没有正确导出或导入
+解决：检查 cdn.js 的 module.exports 和引入语句
+```
+
+### 错误 3: net::ERR_CERT_AUTHORITY_INVALID
+```
+原因：HTTPS 证书问题
+解决：勾选「不校验合法域名...」选项
+```
+
+### 错误 4: 图标显示为裂图/叉号
+```
+原因：
+1. URL 错误（404）
+2. 跨域问题
+3. 图片格式不支持
+
+解决：
+1. 在浏览器中直接访问 URL 验证
+2. 检查服务器 CORS 配置
+3. 确认小程序支持该格式（PNG/SVG）
+```
+
+## 📱 测试命令
+
+在终端测试 CDN 是否可访问：
+
+```bash
+# 测试 logo
+curl -I https://fonts.biboer.cn/assets/webicon.png
+
+# 测试图标
+curl -I https://fonts.biboer.cn/assets/icons/export.svg
+
+# 应该返回 HTTP/2 200
+```
+
+## 🚀 最终检查清单
+
+在提交前确认：
+
+- [ ] 微信开发者工具已勾选「不校验合法域名」
+- [ ] Console 中输出了图标配置信息
+- [ ] Network 中看到了对 fonts.biboer.cn 的请求
+- [ ] 所有请求返回 200 状态码
+- [ ] 图标在页面上正常显示
+- [ ] 手机真机预览也能看到图标
+
+## 💡 下一步
+
+如果以上步骤都检查完毕仍无法显示，请提供：
+1. Console 面板的完整输出
+2. Network 面板的请求列表截图
+3. 是否有任何报错信息

+# apiserver
+
+`apiserver/` 提供微信小程序用的远端渲染接口：
+- 小程序只上传参数（字体 ID、文字、字号、颜色等）
+- 服务端读取 `fonts.json` + `fonts/`，生成 SVG 后返回
+
+## 1. 启动
+
+在仓库根目录执行：
+
+```bash
+python3 apiserver/server.py \
+  --host 0.0.0.0 \
+  --port 9300 \
+  --static-root /home/gavin/font2svg
+```
+
+其中 `--static-root` 目录必须包含：
+
+- `fonts.json`
+- `fonts/`（字体文件目录）
+
+如果不传 `--manifest`，默认读取 `<static-root>/fonts.json`。
+
+## 2. API
+
+### GET `/healthz`
+
+返回服务健康状态和已加载字体数量。
+
+### POST `/api/render-svg`
+
+请求示例：
+
+```json
+{
+  "fontId": "其他字体/AlimamaDaoLiTi",
+  "text": "星程字体转换",
+  "fontSize": 120,
+  "fillColor": "#000000",
+  "letterSpacing": 0,
+  "maxCharsPerLine": 45
+}
+```
+
+成功响应：
+
+```json
+{
+  "ok": true,
+  "data": {
+    "fontId": "其他字体/AlimamaDaoLiTi",
+    "fontName": "AlimamaDaoLiTi",
+    "width": 956.2,
+    "height": 144.3,
+    "svg": "<?xml ...>"
+  }
+}
+```
+
+## 3. Nginx 反向代理
+
+在 `fonts.biboer.cn` 的 server 块中增加：
+
+```nginx
+location /api/ {
+    proxy_pass http://127.0.0.1:9300;
+    proxy_http_version 1.1;
+    proxy_set_header Host $host;
+    proxy_set_header X-Real-IP $remote_addr;
+    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+    proxy_set_header X-Forwarded-Proto $scheme;
+    proxy_connect_timeout 5s;
+    proxy_send_timeout 60s;
+    proxy_read_timeout 60s;
+}
+```
+
+然后执行：
+
+```bash
+sudo nginx -t && sudo systemctl reload nginx
+```
+
+## 4. 约束
+
+- 字体解析完全基于 `fonts.json`，`fontId` 必须存在。
+- 服务端启用 CORS，允许小程序访问。
+- 不依赖 Flask/FastAPI，使用 Python 标准库 HTTP 服务。

+# 小程序图标修复清单
+
+## 修复时间
+2026年2月8日
+
+## 问题
+所有图标在小程序预览中都无法显示
+
+## 根本原因
+1. 使用了相对路径 `../../assets/icons/` 而不是绝对路径
+2. 某些图标文件名包含空格（如 `icons_idx _32.svg`），在某些情况下可能导致路径解析问题
+
+## 解决方案
+
+### 1. 图标路径修复
+所有图标路径已从相对路径改为绝对路径：
+- ❌ 旧: `../../assets/icons/xxx.svg`
+- ✅ 新: `/assets/icons/xxx.svg`
+
+### 2. Logo 更新
+- ✅ 右上角 logo 已改用 `webicon.png`
+- 路径: `/assets/icons/webicon.png`
+
+### 3. 图标映射
+已使用的图标及其用途：
+
+| 图标文件 | 用途 | 位置 |
+|---------|------|------|
+| `webicon.png` | 应用 Logo | 顶部导航栏左上角 |
+| `font-size-decrease.svg` | 减小字号 | 字体大小滑块左侧 |
+| `font-size-increase.svg` | 增大字号 | 字体大小滑块右侧 |
+| `choose-color.svg` | 颜色选择器 | 顶部导航栏右侧 |
+| `export.svg` | 导出选项 | 输入框右侧第一个按钮 |
+| `export-svg.svg` | 导出 SVG | 输入框右侧第二个按钮 |
+| `export-png.svg` | 导出 PNG | 输入框右侧第三个按钮 |
+| `font-icon.svg` | 字体图标 | 预览列表、字体树列表项 |
+| `checkbox.svg` | 复选框选中状态 | 所有复选框 |
+| `expand.svg` | 展开/收起 | 字体分类树 |
+| `selectall.svg` | 已收藏 | 收藏按钮（红心） |
+| `unselectall.svg` | 未收藏 | 收藏按钮（空心） |
+
+### 4. 复选框实现
+由于避免使用带空格的文件名，复选框采用了组合方案：
+
+```xml
+<view class="checkbox-wrapper {{selected ? 'checked' : ''}}">
+  <image wx:if="{{selected}}" class="checkbox-icon-sm" src="/assets/icons/checkbox.svg" />
+</view>
+```
+
+样式：
+```css
+.checkbox-wrapper {
+  border: 1rpx solid #C9CDD4;  /* 未选中：灰色边框 */
+  border-radius: 3rpx;
+}
+
+.checkbox-wrapper.checked {
+  border-color: #9B6BC2;  /* 选中：紫色边框和背景 */
+  background: #9B6BC2;
+}
+```
+
+## 修改的文件
+
+1. **index.wxml**
+   - 所有图标路径更新为绝对路径
+   - Logo 改为 webicon.png
+   - 复选框结构调整
+
+2. **index.wxss**
+   - 添加 `.checkbox-wrapper` 样式
+   - 添加 `.checkbox-wrapper.checked` 样式
+
+## 验证清单
+
+请在微信开发者工具中验证以下内容：
+
+- [ ] 顶部 Logo (webicon.png) 正常显示
+- [ ] 字体大小增减图标正常显示
+- [ ] 颜色选择图标正常显示
+- [ ] 导出按钮组图标正常显示（3个按钮）
+- [ ] 预览列表中的字体图标正常显示
+- [ ] 预览列表中的复选框正常显示（选中/未选中）
+- [ ] 字体选择列表中的展开/收起图标正常显示
+- [ ] 字体选择列表中的字体图标正常显示
+- [ ] 字体选择列表中的复选框正常工作
+- [ ] 字体选择列表中的收藏图标正常显示（已收藏/未收藏）
+- [ ] 已收藏字体列表中的所有图标正常显示
+
+## 注意事项
+
+1. **路径规范**：小程序中使用绝对路径 `/assets/icons/xxx.svg` 会从项目根目录开始查找
+2. **SVG 支持**：微信小程序的 `<image>` 组件支持 SVG 格式
+3. **文件名**：避免使用包含空格的文件名，可能在某些情况下导致问题
+4. **图标尺寸**：所有图标已按照 Figma 设计稿的尺寸设置 CSS
+
+## 如果图标仍不显示
+
+1. 清除缓存：微信开发者工具 -> 工具 -> 清除缓存
+2. 重新编译：点击"编译"按钮
+3. 检查控制台：查看是否有资源加载错误
+4. 验证文件：确认 `/miniprogram/assets/icons/` 目录下所有图标文件存在

+# miniprogram
+
+`miniprogram/` 是 `font2svg` 的微信小程序版本，面向移动端提供字体预览与导出能力。
+
+## 已实现能力
+
+- 文本输入 + 字体选择（搜索/分类/收藏）
+- 远端 API 生成 SVG（服务端读取字体并渲染）
+- SVG 预览
+- 导出 SVG 并调用 `wx.shareFileMessage` 分享
+- SVG 渲染到 Canvas 并导出 PNG，保存到系统相册
+
+## 目录说明
+
+```text
+miniprogram/
+├── pages/
+│   ├── index/                  # 首页：输入、预览、导出
+│   └── font-picker/            # 字体选择页
+├── utils/
+│   ├── core/                   # 纯算法模块
+│   └── mp/                     # 小程序 API 适配层
+├── assets/fonts.json           # 字体清单（由脚本生成）
+├── app.js / app.json / app.wxss
+└── project.config.json
+```
+
+## 使用步骤
+
+1. 在仓库根目录执行 `pnpm run prepare-fonts`，同步字体清单。
+2. 打开微信开发者工具，导入 `miniprogram/` 目录。
+3. 在小程序后台配置合法域名（`request` + `downloadFile`）。
+4. 部署并启动 `apiserver/`（详见 `apiserver/README.md`）。
+5. Nginx 配置 `/api/` 反向代理到渲染服务。
+6. 编译运行。
+
+## 字体清单格式（由服务端解析）
+
+`assets/fonts.json` 每项字段：
+
+- `id`: 字体唯一 ID
+- `name`: 字体显示名
+- `category`: 分类
+- `path`: 字体地址（支持相对路径或完整 URL）
+
+如果 `path` 是相对路径（例如 `/fonts/a.ttf`），服务端会根据静态根目录拼接到实际文件路径。
+
+## 调试命令（仓库根目录）
+
+```bash
+pnpm run mp:syntax
+pnpm run mp:lint
+pnpm run mp:test
+```

+# 小程序 UI 更新日志
+
+## 更新时间
+2026年2月8日（远端渲染改造）
+
+## 本次关键变更
+
+为解决“大字体多预览下载慢”的问题，小程序渲染链路从“本地下载字体并 Worker 渲染”改为“请求远端 API 返回 SVG”：
+
+- 新增 `apiserver/` 目录，服务端读取 `fonts.json` + `fonts/` 并渲染 SVG。
+- 小程序新增 `miniprogram/utils/mp/render-api.js`，调用 `https://fonts.biboer.cn/api/render-svg`。
+- `miniprogram/pages/index/index.js` 移除本地 `loadFontBuffer + worker.generateSvg` 依赖，改为远端渲染。
+- `miniprogram/app.js` 新增全局配置：
+  - `svgRenderApiUrl`
+  - `apiTimeoutMs`
+
+## 兼容性说明
+
+- 字体清单仍使用 `https://fonts.biboer.cn/fonts.json`，字体分类、收藏、导出逻辑保持不变。
+- 导出 PNG 仍在小程序端由 Canvas 渲染，导出 SVG 仍沿用原分享流程。
+
+---
+
+## 更新时间
+2026年2月8日
+
+## 更新内容
+
+根据 Figma 设计稿 (https://www.figma.com/design/S7WVUzg3Z0DMWjYUC6dJzN/font2svg?node-id=584-64) 对小程序首页进行了全面重构。
+
+### 1. 资源文件更新
+
+- **图标素材**：从 web 端 `frontend/src/assets/icons/` 复制了所有 SVG 图标到 `miniprogram/assets/icons/`
+- 新增的图标包括：
+  - 字体大小控制：`font-size-increase.svg`, `font-size-decrease.svg`
+  - 导出功能：`export.svg`, `export-svg.svg`, `export-png.svg`
+  - 颜色选择：`choose-color.svg`
+  - 字体管理：`font-icon.svg`, `expand.svg`
+  - 复选框：`checkbox.svg`, `icons_idx _32.svg`, `icons_idx _34.svg` 等
+  - 收藏功能：`icons_idx _18.svg`, `icons_idx _19.svg`
+
+### 2. 页面结构重构 (index.wxml)
+
+#### 顶部导航栏
+- Logo 展示（星程字体图标）
+- "TextToSVG" 品牌标题
+- 字体大小滑块（带增减按钮）
+- 颜色选择按钮
+
+#### 输入区域
+- 简化的输入框（"此处输入内容"）
+- 导出按钮组（支持 SVG、PNG 导出）
+
+#### 效果预览区域
+- 显示多个选中字体的预览
+- 每个预览项包含：
+  - 字体名称
+  - 复选框（控制是否显示）
+  - 预览图像
+
+#### 字体选择区域（左右分栏）
+- **左侧：字体选择**
+  - 树状分类结构
+  - 支持展开/收起
+  - 每个字体项包含：复选框、收藏按钮
+  
+- **右侧：已收藏字体**
+  - 显示已收藏的字体
+  - 同样支持树状结构
+  - 点击取消收藏
+
+#### 颜色选择器弹窗
+- 预设颜色调色板
+- 自定义颜色输入
+
+### 3. 样式更新 (index.wxss)
+
+- **整体布局**：采用 flex 布局，优化空间利用
+- **颜色方案**：
+  - 主色：`#8552A1`, `#9B6BC2`（紫色系）
+  - 填充色：`#F7F8FA`, `#E5E6EB`
+  - 文字色：`#4E5969`, `#86909C`, `#C9CDD4`
+  - 边框色：`#f7e0e0`
+  
+- **组件样式**：
+  - 顶部导航栏高度：96rpx
+  - 输入框高度：78rpx
+  - 字体树容器高度：360rpx
+  - 圆角设计：12rpx - 24rpx
+  
+- **响应式设计**：
+  - 使用 flex 布局适应不同屏幕
+  - scroll-view 实现内容滚动
+
+### 4. 功能逻辑更新 (index.js)
+
+#### 新增功能
+
+1. **多字体选择**
+   - 支持同时选择多个字体
+   - 每个字体独立预览
+   - `selectedFonts` 数组管理选中的字体
+
+2. **字体分类树**
+   - 自动构建字体分类结构
+   - 支持展开/收起操作
+   - `fontCategories` 和 `favoriteCategories` 管理
+
+3. **收藏功能**
+   - 收藏/取消收藏字体
+   - 收藏状态持久化存储
+   - 已收藏字体独立展示
+
+4. **字体大小控制**
+   - 滑块调整（24-320px）
+   - 增加/减少按钮（步进 10px）
+   - 实时预览更新
+
+5. **颜色选择器**
+   - 弹窗式颜色选择器
+   - 预设颜色调色板
+   - 自定义颜色输入
+
+6. **批量导出**
+   - 导出全部选中字体为 SVG
+   - 导出全部选中字体为 PNG
+   - 单个字体导出
+
+#### 核心方法
+
+- `updateFontTrees()` - 更新字体分类树
+- `onToggleFont()` - 切换字体选择状态
+- `onToggleFavorite()` - 切换收藏状态
+- `onToggleCategory()` - 切换分类展开/收起
+- `generatePreviewForFont()` - 生成单个字体预览
+- `generateAllPreviews()` - 生成所有选中字体预览
+- `exportAllSvg()` - 批量导出 SVG
+- `exportAllPng()` - 批量导出 PNG
+
+### 5. 全局样式更新 (app.wxss)
+
+- 页面背景改为白色
+- 容器高度设为 100vh，支持全屏布局
+- 添加 `overflow: hidden` 避免滚动问题
+
+## 技术亮点
+
+1. **树状结构**：使用 Map 数据结构高效管理字体分类
+2. **性能优化**：字体 buffer 按需加载并缓存
+3. **防抖处理**：输入和调整时使用 260ms 防抖
+4. **状态持久化**：选中字体、收藏状态自动保存
+5. **并发生成**：支持多个字体同时生成预览
+
+## 使用说明
+
+1. **选择字体**：在左侧"字体选择"区域勾选想要使用的字体
+2. **输入文字**：在顶部输入框输入要转换的文本
+3. **调整样式**：
+   - 使用滑块或增减按钮调整字体大小
+   - 点击调色板图标选择颜色
+4. **查看预览**：在"效果预览"区域查看所有选中字体的效果
+5. **导出文件**：
+   - 点击 SVG 图标导出为 SVG 格式
+   - 点击 PNG 图标导出为 PNG 格式并保存到相册
+   - 点击 export 图标可选择批量导出
+
+## 注意事项
+
+- 首次加载字体可能需要一些时间，请耐心等待
+- 建议不要同时选择过多字体，以免影响性能
+- PNG 导出到相册需要用户授权
+- SVG 分享使用系统分享功能
+
+## 后续优化建议
+
+1. 添加字体搜索功能
+2. 支持预览文字大小独立调整
+3. 添加字体加载进度指示
+4. 支持批量框选字体
+5. 优化大字体渲染性能

+	* https://developer.apple.com/fonts/TrueType-Reference-Manual/RM05/Chap5.html
+	*
+	* According to the documentation F24DOT6 values are used for pixels.
+	* That means calculation is 1/64 pixel accurate and uses integer operations.
+	* However, Javascript has floating point operations by default and only
+	* those are available. One could make a case to simulate the 1/64 accuracy
+	* exactly by truncating after every division operation
+	* (for example with << 0) to get pixel exactly results as other TrueType
+	* implementations. It may make sense since some fonts are pixel optimized
+	* by hand using DELTAP instructions. The current implementation doesn't
+	* and rather uses full floating point precision.
+	*
+	* xScale, yScale and rotation is currently ignored.
+	*
+	* A few non-trivial instructions are missing as I didn't encounter yet
+	* a font that used them to test a possible implementation.
+	*
+	* Some fonts seem to use undocumented features regarding the twilight zone.
+	* Only some of them are implemented as they were encountered.
+	*
+	* The exports.DEBUG statements are removed on the minified distribution file.

+	INTERPOLATE:
+	============
+
+	Examples of point interpolation.
+
+	The weight of the movement of the reference point gets bigger
+	the further the other reference point is away, thus the safest
+	option (that is avoiding 0/0 divisions) is to weight the
+	original distance of the other point by the sum of both distances.
+
+	If the sum of both distances is 0, then move the point by the
+	arithmetic average of the movement of both reference points.
