   书签库 · Apple 设计系统（v52）
   ------------------------------------------------------------
   载入顺序：app.css（基础重置 + fadeUp 动画 + 旧变量）→ 本文件（Apple 覆盖）
   本文件同时做两件事：
     ① 定义 Apple 令牌 --a-*，并把旧变量名（--primary/--bg/--text/--line/
        --card/--shadow-* 等）重新映射到 Apple 取值，这样模板里遗留的内联
        `style="color:var(--text-3)"` 也会自动变成 Apple 灰阶；
     ② 覆盖 app.css 的 .btn/.input/.card/.glass/.badge/.alert 等组件为 Apple 样式。
   仅样式层改造：模板 id / 类名 / 内联 JS 逻辑零改动。
