/* ============================================================
   登录页 / 演示控制台
   这两个页面是「整屏应用页」，不走营销站骨架（无顶部广告条 / 导航 / 页脚）。
   所以它们自己带（除了 .btn/.field 等基础件）：
     · 不用额外的装饰 DOM —— 背景辉光直接用 background 的径向渐变画；
     · 全部用 class 选择器，绝对不用 id —— 单文件双语版里同一份页面会内联两次
       （中/英各一份），id 会重复；而且英文份的 id 会被统一加 -en 后缀，
       脚本里写死 id 就会在英文态失联。
