+# Bricks 微信小程序 - 设计文档
+
+## 架构
+JSON → BricksParser → setData → WXML 递归模板 → 小程序原生渲染
+
+## 核心文件
+- `utils/parser.js` - JSON 解析引擎
+- `utils/http.js` - wx.request 封装
+- `utils/renderer.js` - 事件分发
+- `components/brick/brick.wxml` - 递归模板 (template is="brick")
+- `pages/bricks/bricks.js` - 页面入口
+
+## 组件映射
+| Bricks Widget | 小程序组件 |
+|--------------|----------|
+| Text/Title1-6 | `<text class="title-N">` |
+| HBox/VBox | `<view class="flex-row/flex-col">` |
+| Filler | `<view class="flex-fill">` |
+| KeyinText/Input | `<input>` |
+| Image | `<image>` |
+| Running | `<loading>` |
+| VScrollPanel/HScrollPanel | `<scroll-view scroll-y/x>` |
+| Modal/Popup | `<view class="modal-overlay">` |
+
+## 事件系统
+- urlwidget → wx.navigateTo
+- method → Page 方法调用
+- event → bindtap/catchtap
+- script → wx.request 服务端 RPC
+
+## 限制
+- 包体积 2MB → 分包加载
+- WXML 不支持 innerHTML → 用 template 递归
+- Markdown/Html → 需引入 mp-html 插件
