/* =====================================================================
   我的收藏 · 画作索引（Paintings）
   ---------------------------------------------------------------
   这是 collections 分支下的第二个「目录」，和 photographs 平级：
   上面是 collections 四屏里的 02 屏，下面是每幅画自己的页面（待建）。

   现在只是索引壳：六格纯色占位 + 大序号，真画作到位就换图。
   版式刻意做得比摄影那面墙安静 —— 那边是滚动剧场，这边是一页清单。
