/* WR-562k13d (2026-10-16) 手机端「页面内对话框」—— 替换被微信/企业微信 WebView 静默拦截的
   原生 window.prompt() / window.confirm()。
   ----------------------------------------------------------------------
   线上实测根因: 安卓微信/企业微信 WebView 不实现 prompt()(存在但静默返回 null),
   confirm() 也常被拦; 于是「新建文件夹 / 重命名 / 移动到文件夹 / 删除」点了**完全没反应**
   —— 用户看不到任何输入框, 也不会报错, 动作永远不会执行。
   做法: 纯增量, 只提供 Promise 版 wrAsk / wrConfirm / wrChoose(页面内模态), 不改既有函数。
   回滚: 删除本文件 + index.html 里引用本文件的那一行 <script>。 */
