/**
 * WebGPU limits to request when creating the renderer, so VirtualGeometry can use the GPU's full buffer sizes:
 *
 *   const renderer = new THREE.WebGPURenderer({ requiredLimits: await virtualGeometryLimits() });
 *
 * Only needed for single meshes whose cluster hierarchy is larger than 128 MB, the size every WebGPU device supports
 * by default: scans and models of roughly 5 million triangles or more. Smaller meshes, however many, never need it.
 * Pass the same `powerPreference` you give the renderer, so the limits come from the same GPU. Returns `{}` (no extra
 * limits) when WebGPU is not available.
