-# 设计系统迁移指南
-
-> 将现有前端代码迁移到统一设计系统
-
----
-
-## 一、迁移步骤
-
-### Step 1: 引入设计令牌
-
-在 `src/main.ts` 中添加设计令牌导入：
-
-```typescript
-// main.ts
-import './styles/design-tokens.css'  // 添加在最先
-import './style.less'
-// ... 其他导入
-```
-
-### Step 2: 配置 TailwindCSS
-
-更新 `tailwind.config.js` 为 `tailwind.config.ts`：
-
-```bash
-# 删除旧配置
-rm tailwind.config.js
-
-# 使用新配置
-# 已创建: tailwind.config.ts
-```
-
-### Step 3: 配置 Ant Design Vue 主题
-
-更新 `src/App.vue`：
-
-```vue
-<script setup lang="ts">
-import { ConfigProvider, theme } from 'ant-design-vue'
-import { antdThemeConfig, themeManager } from '@gold/styles/antd-theme'
-
-const isDark = ref(themeManager.initTheme())
-const currentTheme = computed(() => themeManager.getAntdTheme(isDark.value))
-
-// 监听系统主题变化
-watchEffect(() => {
-  const media = window.matchMedia('(prefers-color-scheme: dark)')
-  const handler = (e: MediaQueryListEvent) => {
-    if (!localStorage.getItem('theme')) {
-      isDark.value = e.matches
-      themeManager.setTheme(e.matches)
-    }
-  }
-  media.addEventListener('change', handler)
-})
-</script>
-
-<template>
-  <ConfigProvider :theme="currentTheme">
-    <router-view />
-  </ConfigProvider>
-</template>
-```
-
----
-
-## 二、组件迁移示例
-
-### 2.1 颜色迁移
-
-**Before (问题代码)**:
-```less
-// ❌ 组件内定义变量
-@primary: #6366f1;
-@primary-gold: #D4A853;
-
-.button {
-  background: #1890FF;
-}
-```
-
-**After (规范代码)**:
-```less
-// ✅ 使用全局设计令牌
-.button {
-  background: var(--color-primary-500);
-
-  &:hover {
-    background: var(--color-primary-400);
-  }
-}
-```
-
-### 2.2 字体迁移
-
-**Before**:
-```css
-/* ❌ 硬编码字体大小 */
-.title { font-size: 24px; }
-.desc { font-size: 12px; }
-```
-
-**After**:
-```css
-/* ✅ 使用设计令牌 */
-.title { font-size: var(--font-size-2xl); }
-.desc { font-size: var(--font-size-xs); }
-```
-
-### 2.3 间距迁移
-
-**Before**:
-```css
-/* ❌ 魔法数字 */
-.card {
-  padding: 20px;
-  margin-top: 24px;
-  gap: 16px;
-}
-```
-
-**After**:
-```css
-/* ✅ 语义化间距 */
-.card {
-  padding: var(--space-5);
-  margin-top: var(--space-6);
-  gap: var(--space-4);
-}
-```
-
-### 2.4 使用 TailwindCSS
-
-```vue
-<template>
-  <!-- 使用 TailwindCSS 工具类 -->
-  <div class="p-5 rounded-lg shadow-base bg-white">
-    <h2 class="text-lg font-medium text-gray-900">标题</h2>
-    <p class="mt-2 text-sm text-gray-500">描述文字</p>
-    <button class="mt-4 px-4 py-2 bg-primary-500 text-white rounded-base
-                   hover:bg-primary-400 transition-duration-fast">
-      操作按钮
-    </button>
-  </div>
-</template>
-```
-
----
-
-## 三、需要修改的文件清单
-
-### 优先级 P0 - 立即修改
-
-| 文件 | 问题 | 修改内容 |
-|------|------|----------|
-| `src/components/agents/ChatDrawer.vue` | 局部定义 `@primary: #6366f1` | 改用 `var(--color-primary-500)` |
-| `src/components/agents/HistoryPanel.vue` | 局部定义 `@primary: #6366f1` | 改用 `var(--color-primary-500)` |
-| `src/views/auth/Login.vue` | 金色主题 `@primary-gold: #D4A853` | 改用品牌蓝 |
-| `src/views/home/Home.vue` | 硬编码颜色 `#1890FF` | 改用 `var(--color-primary-500)` |
-
-### 优先级 P1 - 短期修改
-
-| 文件 | 问题 |
-|------|------|
-| `src/views/content-style/Copywriting.vue` | 混用 `var(--color-primary)` 和 `#1677ff` |
-| `src/components/GradientButton.vue` | 需要验证与设计系统一致 |
-
----
-
-## 四、批量替换脚本
-
-### 4.1 颜色替换
-
-```bash
-# 在 frontend/app/web-gold 目录执行
-
-# 替换硬编码的主色
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/#1890FF/var(--color-primary-500)/g'
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/#40A9FF/var(--color-primary-400)/g'
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/#6366f1/var(--color-primary-500)/g'
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/#1677ff/var(--color-primary-500)/g'
-```
-
-### 4.2 间距替换
-
-```bash
-# padding: 16px -> padding: var(--space-4)
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/padding: 16px/padding: var(--space-4)/g'
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/padding: 20px/padding: var(--space-5)/g'
-find src -name "*.vue" -o -name "*.less" | xargs sed -i 's/padding: 24px/padding: var(--space-6)/g'
-```
-
----
-
-## 五、验证清单
-
-完成迁移后，检查以下项目：
-
-- [ ] 所有颜色使用 CSS 变量或 TailwindCSS 类
-- [ ] 没有硬编码的 `#xxxxxx` 颜色值（除特殊情况）
-- [ ] 字体大小使用 `var(--font-size-*)` 或 TailwindCSS
-- [ ] 间距使用 `var(--space-*)` 或 TailwindCSS
-- [ ] 组件内没有重复定义 `@primary` 等 Less 变量
-- [ ] 页面视觉效果一致
-- [ ] 深色模式切换正常工作
-
----
-
-## 六、设计令牌速查表
-
-### 颜色
-
-| 用途 | 变量 | 值 |
-|------|------|-----|
-| 主色 | `--color-primary-500` | #3B82F6 |
-| 主色悬浮 | `--color-primary-400` | #60A5FA |
-| 成功 | `--color-success-500` | #22C55E |
-| 警告 | `--color-warning-500` | #F59E0B |
-| 错误 | `--color-error-500` | #EF4444 |
-| 正文 | `--color-text-primary` | #111827 |
-| 次要文字 | `--color-text-secondary` | #4B5563 |
-| 边框 | `--color-border` | #E5E7EB |
-
-### 间距
-
-| 变量 | 值 | 用途 |
-|------|-----|------|
-| `--space-2` | 8px | 图标与文字 |
-| `--space-3` | 12px | 小间距 |
-| `--space-4` | 16px | 标准间距 |
-| `--space-5` | 20px | 卡片内边距 |
-| `--space-6` | 24px | 区块间距 |
-
-### 圆角
-
-| 变量 | 值 | 用途 |
-|------|-----|------|
-| `--radius-sm` | 4px | 标签 |
-| `--radius-base` | 6px | 按钮、输入框 |
-| `--radius-md` | 8px | 下拉框 |
-| `--radius-lg` | 12px | 卡片、弹窗 |
-
----
-
-## 七、常见问题
-
-### Q: 旧组件样式不生效？
-
-确保设计令牌在 `main.ts` 中最先导入。
-
-### Q: Ant Design 组件样式不一致？
-
-检查 `App.vue` 中是否正确配置了 `ConfigProvider` 的 `theme` 属性。
-
-### Q: TailwindCSS 类不生效？
-
-1. 确保 `tailwind.config.ts` 文件存在
-2. 确保 `postcss.config.js` 配置正确
-3. 重启开发服务器
-
-### Q: 深色模式切换有闪烁？
-
-在 `index.html` 的 `<head>` 中添加：
-
-```html
-<script>
-  (function() {
-    const theme = localStorage.getItem('theme');
-    if (theme === 'dark' || (!theme && window.matchMedia('(prefers-color-scheme: dark)').matches)) {
-      document.documentElement.setAttribute('data-theme', 'dark');
-    }
-  })();
-</script>
-```
-
----
-
-> **迁移完成后**，项目将拥有统一的设计语言，后续开发效率将显著提升。
