+// are compiled JS-side at startup (see additional/dom-webgpu.js); the C++
+// side never sees a WGSL handle. This type exists so UIRenderer can
+// declare `WebGPUComputeShader drawQuads;` members for symmetry with the
+// Vulkan side, but `Load()` and `Dispatch()` are intentionally absent —
+// the DispatchQuads / DispatchCircles / etc convenience methods on
+// UIRenderer route directly to the JS bridge.
