/* 链接默认继承文字颜色。
   ⚠️ 这里故意写成 `html a`（特异性 0,0,2）而不是裸 `a`（0,0,1）：
   第三方在线客服脚本（ttkefu）会在页面末尾注入一条无作用域的 `a { color:#000 }`，
   同为 0,0,1 但排在后面，会把全站链接刷成黑色 —— 本站在深色主题下表现为
   「新闻标题/产品卡片/企业卡片/logo 文字全变黑、几乎看不见」。
   `html a` 只比它高一级，能压过第三方裸 `a`，但仍然让位于本站所有 `.class`
   组件规则（`.btn` 是 0,1,0、`.news-list a` 是 0,1,1），所以按钮/胶囊的配色不受影响。
   注意：不要再往上抬特异性（如 `a:link` / `:root a` 都是 0,1,1），那会压过 `.btn`
   把金色按钮上的深色文字刷成浅色。 */
