Research direction
Reproduce the demo site’s WebGPU device initialization and inspect the required limits reported in the error, especially maxBufferSize. The payload names no source files or tests, so first locate the demo’s device setup and determine whether the error is reproducible in the target browser. Done means the demo initializes successfully or clearly reports the supported-limit constraint and its workaround.
