THREE.JS / GEOMETRY CONTRACT
One box, two shapes.
The official morph-target study stores alternate vertex positions in geometry.morphAttributes.position, then drives them through mesh.morphTargetInfluences. This lab exposes the native spherical and twist targets as independent, measurable controls.

The official morph-target construction is preserved with an explicit native WebGPU lane and a WebGL2 reference lane. The study HUD, not the official lil-gui/Inspector presentation, is the local contract. Native device/compiler/backend coverage, context-loss stress, and whole-example fidelity remain separate boundaries.
