/* ============================================================
   内嵌演示窗（#demo 区块的 .demo-player）
   ------------------------------------------------------------
   为什么是内嵌 DOM 而不是 GIF/视频：
     1) 零带宽 —— GIF 要 2–6MB，首屏直接被拖垮；
     2) 移动端不卡 —— 没有逐帧解码；
     3) 不会过期 —— 产品改版后改几行 HTML 即可，不用重录；
     4) 表格里的日期/金额是引擎对内置示例账单的真实输出，不是示意数据。
   配色与 .demo-beat / .classify-demo 同族（emerald accent + slate），
   不引入新色板。
   若日后录了真实操作视频：把 index.html 里整个 .demo-player 换成
   <img src="assets/img/demo.gif" alt="...">，并去掉 .has-player，
   本节样式即可整段删除。步骤见 README §Recording the demo。
