/* ============================================================
   AIPicks 2.0 —— 主样式表

   组织顺序：
     1. 主题变量（浅色 / 深色）
     2. 基础重置与排版
     3. 布局骨架（头部 / 主区 / 页脚）
     4. 组件（按钮、卡片、评分条、标签、开关…）
     5. 视图专属（首页 / 工具库 / 对比 / 排行 / 方法论）
     6. 浮层（抽屉 / 弹窗 / 对比托盘）
     7. 响应式断点

   约定：
     - 颜色一律走 CSS 变量，不写死色值，方便换主题
     - 尺寸用 rem / 百分比，少用 px 硬编码
     - 需要新增主题只改 :root 与 [data-theme="light"] 两处
