What is Augmented Vertex Block Descent (AVBD)?

AVBD's a solver for rigid/soft-body physics—uses block-wise descent on vertices, augmented with duals and stiffness ramps for faster, parallel convergence. From Giles et al. 2025; crushes traditional methods on GPUs.

How do I run the WebGPU AVBD physics demo?

`npm install`, then `npm run dev`. Chrome Canary recommended—heads up, experimental, no broad browser love yet.

Will WebGPU physics like this work in production games?

Soon. Polish incoming: stability, multi-browser, soft-body polish. Game-changer for web-first titles, but iterate carefully now.
