/* ============================================================
   「小游戏」这一节（index.html #games）：不论站点主题，都是一块合成波（synthwave）夜景。
   - 背景：整节两层飘动的像素尘；转盘后面一轮条纹落日 + 往前滚的霓虹网格地面（只铺在转盘这一块，不压下面的文字）；
   - 中间：8 张游戏截图排成一个 3D 转盘，慢慢转，指针悬停时停住、跟着指针倾斜、可以拖着转（assets/games.js 逐帧写 .gm-ring 的 transform）；
   - 下面：数字卡（计数动画沿用 app.js 的 data-count）、特性卡、接入代码。
   只动 transform / opacity / background-position，不触发重排。
   不要动画（prefers-reduced-motion）或窄屏：转盘拆成一排可横滑的静态卡片。
