   R14-T (2026-04-22) · 夺回被 bootstrap 劫持的短名 token
   ============================================================
   critical.html 加载顺序:
     tokens.base → theme-N → aoyun.css → color-override → complete-theme
     → bootstrap.min.css → font-awesome → custom.css
   aoyun.css L7085/L10185 把 --primary 桥到 --color-primary (theme-aware),
   但 bootstrap.min.css 之后的 :root { --primary: #007bff; } 把桥砸了 (同 :root
   特异性, 后声明胜). 用户看到的 .faq-detail-link 冷蓝按钮、任何 var(--primary)
   的消费者都被它吃掉.

   custom.css 是最后加载的文件, 在这里 :root 重新声明 5 个短名 token, 彻底压住
   bootstrap 的遗留 hex. 5 个名字都是 bootstrap 4.4 style guide 的保留名:
     --primary  / --danger  / --warning  / --info  / --success
   ============================================================ */
:root {
    --primary:  var(--color-primary);         /* R14-T: 原 bootstrap #007bff 蓝 */
    --danger:   var(--color-danger);          /* R14-T: 原 bootstrap #dc3545 */
    --warning:  var(--color-warning);         /* R14-T: 原 bootstrap #ffc107 */
