/**
 * Paper-6 WebGPU Cross-Backend Matrix Benchmark — browser entry point.
 *
 * Imports the canonical AnimationSamplingProbe, runs it in the browser,
 * detects environment (browser / OS / GPU), measures per-stage latency,
 * computes the FNV-1a hash, and exposes the artifact on
 * window.__PAPER6_WEBGPU_ARTIFACT__ for the Playwright harness to capture.
 *
 * Build:  pnpm run build:paper6-bench
 *         (esbuild bundles this entry into benchmark-paper6-webgpu.js)
 *
 * Run:    npx playwright test tests/paper-6-webgpu-matrix.spec.ts
 *         (or open benchmark-paper6-webgpu.html directly in a browser)
