### Task 15: 改善可访问性

**文件:**
- 修改: `src/components/ui/*.tsx`
- 修改: `src/app/(marketing)/**/page.tsx`

**Step 1: 添加ARIA标签**

为所有交互元素添加适当的ARIA标签：

```typescript
<Button 
  type="submit" 
  data-testid="submit-button"
  aria-label="提交联系表单"
  disabled={isSubmitting}
>
  {isSubmitting ? '发送中...' : '发送消息'}
</Button>
```

**Step 2: 改善键盘导航**

确保所有交互元素可通过键盘访问：

```typescript
// 添加键盘事件处理
const handleKeyDown = (e: React.KeyboardEvent) => {
  if (e.key === 'Enter' || e.key === ' ') {
    e.preventDefault();
    handleClick();
  }
};

<div
  role="button"
  tabIndex={0}
  onKeyDown={handleKeyDown}
  onClick={handleClick}
  aria-label="点击执行操作"
>
  内容
</div>
```

**Step 3: 优化颜色对比度**

确保文本和背景颜色符合WCAG AA标准：

```css
/* 确保对比度至少为4.5:1 */
.text-primary {
  color: #1C1C1C; /* 与白色背景对比度 > 4.5:1 */
}

.text-secondary {
  color: #5C5C5C; /* 与白色背景对比度 > 4.5:1 */
}
```

**Step 4: 添加跳转链接**

为键盘用户提供跳转链接：

```typescript
// 在layout.tsx中添加
export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="zh-CN">
      <body>
        <a 
          href="#main-content" 
          className="sr-only focus:not-sr-only focus:absolute focus:top-4 focus:left-4 bg-white px-4 py-2 rounded shadow-lg"
        >
          跳转到主要内容
        </a>
        <main id="main-content">
          {children}
        </main>
      </body>
    </html>
  );
}
```

**Step 5: 运行可访问性测试验证改进**

```bash
cd test-framework
npm run test:dev-audit:accessibility
