Look inside the render loop.

The official Inspector is a live WebGPU debugging surface: it attaches to the renderer, records frame structure, exposes parameter controls, and previews named TSL nodes. This lab makes those ownership and teardown boundaries explicit.

The probe will exercise the render loop, parameter GUI, Viewer node capture, panel visibility, and release.

Inspector GPU timings depend on the optional timestamp-query feature; frame topology remains the primary contract.
