   v24 · 作品展示：图片按原比例完整呈现（零裁切）+ 混乱错落
   ----------------------------------------------------------------
   原来那套「固定行高网格 + background-size: cover」会裁图：
   1.86:1 的横图被切成竖的，1:1.5 的竖图被切成横的，观众看到的
   从来不是照片本来的构图。

   现在的做法：
     · 容器换成多列瀑布流，卡片高度由图片自己撑开；
     · 缩略图改用 <img>，width:100% + height:auto → 原比例，不裁一个像素；
     · 拿掉卡片的碎片切角（clip-path 会连带切到图片）；
     · 混乱感靠「宽度不一 + 左右偏移 + 角度不一 + 上下间距不一 + 浮动」来造。
