Works fine if I swap to WebGPU
Tried Ctrl F5 to no effect

Do we have a way to prohibit an example from webgl but not webgpu? We could just disable this example on web entirely but it does work on webgpu.

[JMS55]

This example isn't supposed to run on webgl, we need some way of disabling it. Ideally splitting up our wasm=true cargo.toml configs, but maybe just having the example code detect when storage buffers aren't available and throw some "not supported" UI text up.
