MANUAL STUDY / SCENEGRAPH
Parent the idea.
Build orbital frames, attach a turret, and let world transforms explain why hierarchy beats coordinate copying.
Preparing scenegraph—
Creating nested Object3D frames and attached cameras…
The sun’s visual scale stays separate from Earth’s orbital distance.
Attached cameras inherit the parent’s transform; detached mode keeps camera control independent.

Scenegraph study failed.The renderer could not initialize.
Drag to orbit in detached mode. Watch the world-position metric while switching between the scaled-parent trap and fixed frames.
