/* =====================================================================
   学阅平台登录页样式 v3.6 —— 2026-09-19 忘记密码弹窗交互
   设计要点: 高透玻璃大卡片(背景清晰透出) + 等高面板(页签切换零跳动) +
            面板原生完整边框(四角连续圆弧) + 页签描边/居中下划线 +
            按钮循环扫光 + 页面级氛围动画
   v3.5: 新增 :-webkit-autofill/:autofill 规则,浏览器自动填入账号密码时
         输入框观感与手工输入一致(盖住内部浅蓝底色,恢复白字/白图标)
   v3.6: 找回密码弹窗改为屏幕居中;预设问题/问题答案 label 后支持红色
         行内提示(旋转小图标+文字);新密码框默认禁用由 JS 按验证结果启用
   说明: 类名/ID 与 login.js、example.js 的选择器保持兼容;
        #userLogin/#login_container 的显隐由内联 style 切换,这里只做外观。
