Soft light, explicit dimensions.

The source initializes RectAreaLightUniformsLib, places three colored RectAreaLight instances around a reflective torus knot, and keeps their width, height, intensity, and helper geometry inspectable. This contract retains that native WebGL light path with deterministic local geometry.

This is a native RectAreaLight contract, not the official page’s exact camera, checker scale, torus-knot framing, Stats presentation, or pixel composition. Asset parity, device performance, backend parity, context-loss stress, and whole-example fidelity remain separate boundaries.
