+  draggable target empties and debug gizmos. A lidar-material scene puts glass, water, mirror
+  and retroreflector panels in front of a diffuse backstop, exercising the NIR material model:
+  the voxel bake that maps a collision hit back to its Hazel material, per-return intensity and
+  range-calibrated reflectivity, and pass-through secondary returns off the wall behind.
