    worldMatrix: Mat4;
    worldMatrixVersion: number;

worldMatrix worldMatrixVersion
worldMatrix: Mat4

World-space 4×4 column-major matrix. May trigger lazy recomputation.

worldMatrixVersion: number

Monotonically increasing counter — bumped each time worldMatrix recomputes. Children snapshot this value to detect when their parent has changed. Must never decrease: _cameraChangeKey sums it with the projection revision and relies on that to detect every change without aliasing.
