/**
 * WebGPU Physics Smoke / Benchmark — browser entry point.
 *
 * Runs the existing WebGPU particle-physics pipeline at 1K, 10K, and 100K
 * particles, measures per-step wall time, and exposes a machine-readable
 * artifact on window.__WEBGPU_PHYSICS_ARTIFACT__ for the Playwright harness.
 *
 * Build:  pnpm run build:webgpu-physics-bench
 *         (esbuild bundles this entry into benchmark-webgpu-physics.js)
 *
 * Run:    pnpm run benchmark:webgpu:physics
 *         (or open benchmark-webgpu-physics.html directly in Chrome)
