**Returns:**

## Remarks

\*\*Coordinate system:\*\* Identity rotation (0,0,0,1 quaternion) means facing -Z. For Y-axis rotation only (yaw), use: `{ x: 0, y: sin(yaw/2), z: 0, w: cos(yaw/2) }`<!-- -->. A yaw of 0 faces -Z, positive yaw rotates counter-clockwise when viewed from above.

This sets rotation immediately. For smooth rotation, use angular velocity (dynamic) or next kinematic rotation (kinematic).
