   模态框显隐

   关键：不能用 display 控制显隐。
   display:none → display:flex 是在同一帧内完成的二值跳变，

   改用 visibility + opacity：
   元素始终留在渲染树里，transition 才能正常插值。
   visibility 用延迟切换（关闭时等动画结束再变 hidden），

   这类按钮的结构是 [纸飞机图标] + [文字]，没有 .btn-spinner。
   因此必须覆盖通用的 .btn.loading 规则：那条规则会把文字与图标
   全部 display:none，只等一个不存在的 spinner 出现，
   结果按钮在加载时变成一片空白。

   这里改为：加载时保留文字，仅让纸飞机脉动前进；
   完成后按钮转绿、图标放大，给出明确的结束反馈。

     .modal-overlay.active .modal   (0,3,0)
     .modal-overlay.closing .modal  (0,3,0)

   改为「只在切换的那一刻」临时挂上过渡类：
     html.theme-transition * { transition: ... }
   切换完成后立刻移除，稳定状态下零开销。
   过渡计时由 config.js 的 setTheme() 控制。
