让角色的头部沿一条平滑、连续的上半弧线运动，从第一帧中的左上朝向转到最后一帧中的右上朝向。头部自然地走完整条弧线。躯干、肩膀、西装以及整体身体…

"Animate the character’s head through one smooth, continuous upper arc from the top-left orientation in the first frame to the top-right orientation in the last frame.

No body translation, no camera movement, no zoom. Smooth, controlled, continuous motion."
