- Introduced StageGizmos for hover highlighting, selection outlines, and rotation handles in the sandbox stage builder. - Added StageGrid for an optional world-space grid overlay that adjusts with camera panning and zooming. - Implemented StageSelection for geometric hit-testing and selection management of nodes in the sandbox. - Created StageSpawner as a registry-driven factory for spawning terrain, props, and stickmen, allowing for dynamic template management. - Each script includes necessary constants, state management, and public API methods for interaction.

## StageGrid - Optional world-space grid overlay for the Sandbox Stage Builder.

##

## Draws grid lines that pan/zoom with the camera, with a heavier major line
|
|
## every few cells. Pure drawing; no hit-testing. Rendered behind the World by

## keeping this node as the first child of the stage root.
