/* 二维码弹窗：左右两栏
   左栏卡片原尺寸完整显示，右栏编辑项自己滚。

   为什么必须两栏：上下排的话，卡片和编辑区抢同一份垂直高度，
   而卡片是「不许收缩」的那一方 —— 窗口一矮就必然被裁掉底栏
   （或者反过来把编辑区挤到压住底栏按钮）。
   两栏各占一边，谁也不用跟谁抢。

   注意 display 只能写在 [open] 上。
   UA 样式表里是 dialog:not([open]) { display:none }，用来让未打开的弹窗隐藏。
   而作者样式优先级恒高于 UA 样式，所以只要写成
       .dlg-qr { display: flex }
   就等于把那条 display:none 顶掉了 —— 弹窗关着的时候照样显示，
   以普通流的形式压在工作台上：没有遮罩、内容互相重叠、
   而 openQr() 里画二维码的代码压根没执行（因为从没 open 过）。 */
