Browser Support

GPU construction and queries in the browser require WebGPU.

CPU builds (build_cpu) work in any browser that runs WebAssembly — WebGPU is only needed for the GPU build path (build_gpu).

Checking at runtime

if ("gpu" in navigator) {
  // WebGPU available — build_gpu will work
} else {
  // Fall back to build_cpu
}

The live demo does exactly this: it detects WebGPU, shows a badge, and enables or disables the GPU build button accordingly.
