/* 7MGO-REGISTER-CURRENT-PAGE-RESPONSIVE-FIT-FIX: 注册页响应式适配修复（仅尺寸/布局/高度）。
   视觉方案保持不变：7mgo Logo / ACCESS REQUEST / 标题 / 表单内容 / 配色体系 / 右侧数据图 /
   3 条说明 / Footer 文案，一律不改。本文件只负责：
   1) 页面高度结构（html/body/.page-shell flex，Main flex:1，Footer 落底）；
   2) Desktop 主容器/面板随视口放大（clamp 尺寸，禁止 transform:scale/zoom）；
   3) Mobile 独立单栏布局（<=768px 右视觉隐藏），无横向溢出。 */
