   产品视觉组件 —— 用「产品自己的样子」当图片
   ══════════════════════════════════════════════════════════

   为什么不用图库照片:
   统计工具的客户想知道的是「看板长什么样、我能看到什么数据」。
   一张办公室握手照回答不了这个问题,只会让页面更像模板站。
   所以这里的每一个「图」都是用 HTML + SVG 拼出来的产品界面 ——
   矢量、零外部请求、跟着主题变色、还能动。

   为什么不用真实截图:
   截图会随着产品迭代过期,而且在高分屏上糊、暗色模式下不对、
   移动端裁剪困难。拼出来的组件永远和当前设计系统一致。
