// GPUProviderModule for gpuweb/cts's tools/run_node (--gpu-provider).
// Wraps the prebuilt dawn.node binding shipped by the "webgpu" npm package
// (dawn-gpu/node-webgpu), so the CTS's own runner drives Dawn directly with
// no browser involved. Vulkan driver selection happens outside this file,
// via VK_ICD_FILENAMES/VK_DRIVER_FILES pointed at lavapipe before node starts.

// the IDL constructors as globals (true in a browser, where they hang off
// `window`); dawn.node only hands them back from create(), so they have to
// be installed onto globalThis here or every such check throws
// ReferenceError before any test runs.
