/* ============================================================
   Tools Arco Design 官网风格覆盖样式
   参考 https://arco.design/react/docs/start
   
   核心原则：
   - 去掉卡片容器 — 内容直接铺在白色背景上
   - 用标题层级 + 间距分隔内容段落
   - 保持组件的 Arco 风格（输入框、按钮、Tab 等）
   - 配色使用 Arco 色值：文字 #1D2129 / #4E5969 / #86909C，
     强调 #165DFF，边框 #E5E6EB，背景 #F7F8FA
