One GLB carries geometry, collision hulls, mass, inertia, bonds, hierarchy, and materials.

Click the model to shoot a sphere. Pieces start asleep and wake on impact. Reset reloads 16 shots. Bonds are visualized, not solved for stress. Experimental convex contacts; this demo is not a 10,000-body performance benchmark.
