本次移植直接参考用户提供的「翅膀_伊甸威能兼容.zip」中的
me.paulf.wings.client.camera.CameraAnimator 及相应渲染注入。
该源码注明过渡动画本体来自 Nimble（Snownee，MIT）；不是将 Wings
整个项目或其其它功能声明为 MIT，也不是将该算法归为 Eden Power 原创。

适用代码：PetMountCameraTransition 的距离推进与正弦插值，以及
PetMountCameraAnimation / PetMountCameraOptionsMixin / PetMountCameraFade
中从该实现改编的显示视角分离和模型透明度机制。
本工程改动：限定逐宠物骑乘边界、支持中途反向、保留原版避墙与距离事件，
将淡出改成单次玩家绘制的缓冲包装，并加入可选 Wings 相机协调。
