WebGPU is optional for the explicit WebGL2 path. An API being present does not guarantee a usable adapter or a full engine initialization. Worker and shared-memory checks are relevant to engine paths but cannot prove that the captured engine will start.

Storage is the browser’s approximate origin-wide estimate. It can include other data and can change. The checker does not allocate a map-sized file, benchmark your GPU or request persistent storage.
