/* ==========================================================================
   平台入口：立体舞台（静止就有前后关系，不依赖悬停）
   --------------------------------------------------------------------------
   插画自带一块不透明浅灰底，无法干净抠掉，因此不再做"透明贴图"，改为：
   · 画框是一块有纵深的光台（中心亮、四周压暗）
   · 插画作为"悬浮屏"浮在台上：轻微倾角 + 圆角 + 双层投影
   · 屏下方有接地投影，随浮动轻微缩放（呼吸），循环播放
   · 悬停时整卡跟随光标倾斜并抬起
