/* ================= 小程序五页面互动展览 =================
   两层结构，严格分开（这是上一版没做对的地方）：

     外部展览容器 .ex-viewport / .ex-stage
       占满桌面宽度，负责横向排列、切换、两侧露出邻页。

     内部小程序页面 .ex-page
       固定 **375 × 812pt** 的竖屏视口（原工程设计基准），
       内部一律按 pt 绝对布局，**不跟随外部容器宽度重排**；
       整页靠 JS 设置 transform:scale() 统一缩放，宽高同比。

   原工程基准（核对结果，见 exhibition-data.js 注释）：
     ui格式.psd / 收藏室.psd = 1125 × 2436（iPhone X 三倍图）
     → 375pt × 812pt，微信 750rpx，**1rpx = 0.5pt**
   源码里的 rpx 数值一律 ×0.5 得到这里的 pt 值。

   只做电脑端；侧页本轮只整体缩小 + 轻微压暗，取消旋转。 */
