/* auth.css — 登录 / 注册 / 修改密码 共享样式
   Apple 设计语言:
   - 中性灰页面底 (#f5f5f7) + 顶部极淡蓝色氛围光,单张悬浮白卡 (18px 圆角 + 柔和分层阴影)
   - 分组式灰底输入 (46px 高 / 12px 圆角),聚焦蓝色光环
   - 胶囊主按钮 (48px),按压 scale 反馈
   - 卡片入场 250ms Apple 曲线 cubic-bezier(0.32, 0.72, 0, 1)
   仅覆盖三个认证页面,不动 app.css 的全局视觉系统。
   注意:认证页不加载 app.css,所有缓动/时长在此内联。
