   登录 / 注册 / 找回密码 · 轨道控制台版（2026-11-08 v2）
   --------------------------------------------------------------------------
   设计方向：把「营销落地页 + 白卡片」改成「航天任务控制台」
   · 左侧：HUD 取景框（四角括号 / 细网格 / 扫描线）+ 等宽字技术标签
           标题改为超大字号紧凑字距，指标从玻璃卡片改成「仪表读数格」
   · 右侧：蓝图网格底 + 极细线分隔，卡片顶部加安全状态条，
           主/子 Tab 从胶囊按钮改成下划线式（更像仪器面板），
           表单标签带 01/02 编号，按钮带方向箭头
   · 全部动效只跑 transform / opacity，遵循 prefers-reduced-motion
   --------------------------------------------------------------------------
   注意：本页 html{font-size:100px}，rem 会被放大 100 倍，全部改用 px / clamp / vw
