THREE.JS / FOUNDATIONS 172

Sort the swap.

A bitonic network turns a shuffled power-of-two buffer into an ordered field. Watch each local and global compare stage become a renderer-visible contract.

The native lane follows the official 16,384-element stepwise BitonicSort helper beside the official global-storage swap shape. A forced-WebGL2 run keeps an explicit CPU proxy; Three.js does not claim compute shader parity on that backend.

Green-to-violet values are ordered from low to high · the native lane follows the pinned official 16,384-value dual-WebGPU shape.
