   独立门户（学目思 AI 学习中心）· 登录页 + 入口页 共用样式
   双色锁定：亮=粉金 / 暗=Mercury；token 全部取自 css/xms-theme-dual.css。
   部署形态：门户与 school_grades.html 同层（webroot 的 adaptive-learning-loop/web/ 下），
   故主题文件挂 ../../css/xms-theme-dual.css；直接本地打开时为预期死链
   （同 school_grades.html 先例），token 走下方
   亮色锁定值 fallback，不另起第三主色、不写暗色硬值。
   禁止卡顶细色条；禁止假数据；禁止三等分图标卡落地页。
