/* =====================================================================
   Voyager · DarkStar — 页面框架 + AI 对话(仿 DeepSeek 网页版)+ 手机端适配
   站主要求:
     ① 三条杠 + 我的 固定右上角(见 nav.css);
     ② 入口页全屏、可展开可收缩(见 entry.css);
     ③ AI 对话仿 DeepSeek:窄列居中、回答无边框、输入区悬浮圆角、消息留白;
     ④ 论坛全屏(占满视口、内部滚动);
     ⑤ 卡牌浏览的筛选条常驻顶部(sticky top:0);
     ⑥ 手机版 UI 重做:单列、输入吸底、字号下调。
   本文件最后加载,只覆盖视觉与布局,不动任何后端逻辑。
