/* ========== 搜索框容器（2026-09-27 改版：输入框与按钮合成一体） ==========
   旧样式是「灰底大盒子（#e2e8f0 + 20px 内边距）里放一个白输入框和一个蓝按钮」——
   三块各自有边框/底色，读起来像三个独立控件，而不是「一个搜索框」。
   现在：容器透明（那层灰底不表达任何信息，是纯视觉噪音），
   白底 + 细描边的**长方形（小圆角）**只画在 .zib-*-search-box 上，
   输入框无边框、按钮嵌在右端。
   宽度：外面那层容器上限 960px，这里再收到 **480px（一半）并居中** ——
   搜索框只需要够输入的长度，撑满整行会把「输入 + 按钮」这对关系拉散。
   ★ 只缩这一层、不缩 .zib-*-search-container：搜索结果列表要照旧占满 960px，
     一起缩窄会让结果行的表头/文件名/按钮挤在一起。
   ★ 深色模式的对应规则在文件下方的「夜间模式支持」一节，两处要一起改。 */

   ★ 用 :focus-within 让「点进输入框」时高亮的是**整个搜索框** ——

   ★ 形状是「长方形带一点圆角」：外壳 8px，内部两件 4px。
     内部圆角 = 外壳圆角 − padding（8 − 4）—— 给大了按钮的角会从外壳的弧里
     探出来，给小了按钮四角会出现一圈白缝。 */

/* ========== 搜索：不闪屏加载态 + 慢搜索提示（2026-09-27 新增） ==========
   为什么需要这一节：OpenList 未建索引时，一次 fs/search 是一次真实的目录遍历，
   动辄十几秒。原实现每次搜索都先把结果区整块换成「正在搜索...」——
   用户看到的是「内容消失 → 一片空白 → 内容出现」，比慢本身更难受，
   而且页面高度剧烈跳动，正在看的那一行会跑掉。
   现在：有旧结果可留时只压暗 + 禁止点击（容器上的 .is-searching），
   只有首次搜索（还没有结果）才显示转圈块。

   放在文件末尾是为了不被上面 1400+ 行里的同名规则意外覆盖；
   深色主题的覆盖紧跟在同一处，避免以后加主题时漏掉这一节。 */

/* ==========================================================================
   点击后的即时反馈：「获取中…」
   --------------------------------------------------------------------------
   为什么非要有这一层：点一次下载（或预览），后端最坏要串 3 次上游
   （fs/link → fs/get → admin/setting/get），慢的时候好几秒。
   期间界面**毫无变化**，用户的结论必然是「点了没反应」，于是再点一次 ——
   而第二次会被管理器里的 downloading / previewing 锁直接吞掉，
   表现成「点了两次都没反应」，看起来更像坏了。
   所以：点击后立刻在被点的那一项上盖一层「获取中…」。

   ★★ 目录树（.zib-file）**故意不在名单里** —— 这是用户明确要求的
      （「点击目录树 pdf 文件名不要显示加载中」）。
      理由不只是「不想要」：树里的行是紧凑型（padding 3px 8px /
      min-height 22px / font-size 13px），铺满整行的纱会**把文件名整个盖掉**，
      而文件名正是用户刚点过、要用来确认「我点的是哪个文件」的东西。
      预览侧另有面板级的反馈（右侧查看器本身在加载），
      所以树这一行不给反馈并不会让人以为「点了没反应」。
      ★ 以后要加回来，先把这段读完 —— 这是取舍，不是漏写。
      JS 侧对应的是 main.js 里「树文件点击故意不传 el」那处注释。

   ★ 文案走 ::after，绝不用 JS 改 text()：被点的是**整行**，
     里面有文件名、图标、大小、按钮，改文字会把它们全抹掉。
   ★ 用「铺满整行的纱」而不是角落小徽标：角落徽标会和右侧的
     大小列 / 下载按钮打架（徽标比按钮宽），只能靠隐藏按钮 + 加
     padding 去躲，反而把行宽搞跳。铺满整行则完全不依赖子元素布局。
   ★ 纱的颜色走 CSS 变量，深浅主题只改两个变量值 —— 否则这里要写
     7 种主题根 × 3 个元素选择器 = 21 条规则。

   ★ position:absolute + top/right/bottom/left:0 不是为了炫技：
     .preview-panel 是 column flex，而 .preview-welcome 与 .pdf-viewer-container

     查看器 iframe 本来就是 position:absolute 相对 .preview-panel 定位的，

   ★ 这里的 height 由 top/bottom:0 决定，不再写 height:100%（写了两者会打架）。
