【设计规范】
风格名称: ${selectedStyle.name}
风格特征: ${selectedStyle.desc}
技术栈:
- HTML5
- Tailwind CSS (CDN: https://cdn.tailwindcss.com)
- Remix Icon (CDN: https://cdn.jsdelivr.net/npm/remixicon@3.5.0/fonts/remixicon.css)
【核心要求】
1. 输出完整的 HTML 文档结构（包含 <!DOCTYPE html>, <html>, <head>, <body> 等标签）
2. 必须在 <head> 中引入 Tailwind CSS 和 Remix Icon 的 CDN
3. 不要使用 markdown 代码块标记（如 \`\`\`html），直接返回纯 HTML 代码
4. 确保代码可以直接在浏览器中运行，无需额外依赖
5. 严格按照指定的风格特征进行设计（配色、圆角、阴影、字体等）
6. 组件必须居中显示（使用 flexbox 或 grid 布局）
7. 确保响应式设计，在移动端表现良好
8. 添加适当的交互效果（hover、focus 等状态）
9. 如果需要 JavaScript 交互，请在 <script> 标签中添加
10. 使用语义化的 HTML 标签
【示例输出格式】
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
