+/// <summary>
+/// 按屏幕宽高比动态拉长轨道视觉物体(track1-5)的 Y 缩放,让宽屏下轨道更饱满。
+///
+/// 原理：宽屏时水平视野大、轨道相对缩在中间显细。降相机高度+抬头能让轨道透视放大,
+/// 但仍不够饱满。再叠加"拉长轨道 Y 缩放"填满纵向视野,视觉更满。
+///
+/// 关键：轨道只是背景视觉,判定是几何驱动(音符世界 Y vs 判定线世界 Y)。
+/// 缩放轨道 localScale 不影响音符生成/下落/判定——它们全用世界坐标,与轨道视觉无关。
+///
+/// 用法：挂到场景任意物体(会自动找 track1-5 或指定 trackParent)。运行时自动扫描并缩放。
