A 3x3x3 grid of AABB-geometry spheres rendered through an analytic ray-sphere intersection shader, with an any-hit spherical-checkerboard cut-out so the background shows through. Exercises both features end to end on the WebGPU wavefront tracer. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
