Adapter Detection

// Core adapter — requires Vulkan / Metal / D3D12
const coreAdapter = await navigator.gpu.requestAdapter({
  featureLevel: "core"
});

// Compatibility adapter — works on OpenGL ES 3.1 / D3D11
// (Origin trial in Chrome 148)
const compatAdapter = await navigator.gpu.requestAdapter({
  featureLevel: "compatibility"
});

// Fall back gracefully
const adapter = coreAdapter ?? compatAdapter;
if (!adapter) {
  // WebGPU not available on this device at all
}

// Check what you got
const info = await adapter.requestAdapterInfo();
console.log(info.vendor, info.device, info.architecture);
