</section>安装
在页面中引入组件样式与 Tailwind 配置即可。组件样式只包含组件本身，不包含站点外壳。
<link rel="stylesheet" href="design-system/assets/design-system.css" />
<script src="https://cdn.tailwindcss.com"></script>
<script src="design-system/tokens/tailwind.config.js"></script>使用方式
在 Code 标签页复制完整标记，替换其中的文案与数据即可。颜色、字号、圆角与阴影一律引用 tokens/design-tokens.json 中的 token，不要写入未定义的颜色值。
组件在浅色主题下设计；若页面启用暗色模式，请先用 token 覆盖背景与文字色，再复用组件结构。
设计规范
完整的尺寸、状态与反模式说明见 DESIGN.md。开发完成后请按 §28 检查清单逐项核对。
