   --------------------------------------------------------------------------
   【真实 DOM —— 与初稿假设不同，这是本版重写选择器的依据】

   .verify-container
     └ .search-card
         ├ .card-header  → h1 + p            （原本是深紫渐变 + 白字）
         └ .card-body
             ├ .search-tabs > .tab × 5       （div，不是 <select>）
             ├ .input-group > label + input[type="text"]
             └ button.btn-search             （无 type 属性，不是 [type="submit"]）
     ├ .result-card / .not-found-card
     └ .info-section

   ⚠ 页面没有 <form>、没有 <select>、按钮也没有 type="submit"。
     初稿中 `.verify-container form` / `form::after` / `button[type="submit"]`
     三组选择器在真实 DOM 上均为死规则，故本版以 .search-card / .card-body
     作为卡片载体，以 .card-body::after 承载官方声明。
   ⚠ 原 .card-header 是 #4A3A6B→#2c2345 深紫渐变。若保留深紫底而把
     h1 改成 #1F2937，对比度仅约 1.6:1（WCAG AA 要求 4.5:1），标题会不可读。
     故卡头一并改为白底，这也更符合“白卡片 + 深色衬线标题”的既定意图。
   --------------------------------------------------------------------------
   作用域：全部选择器均以 .verify-container 前缀收敛，不波及其它页面。
