It looks like you're right - the announcement tweet credits threejs and houdini [1]. I measured 13MB downloaded, of which most are fairly bloated "assets" (here's a 3MB blurry png, for some reason [2]), so the "engine" itself looks to be less than 1MB.

That blurry png may be the terrain, height map?

The filename says "clouds" but either way, whatever it's used for, the information in it really doesn't need 3 MB of pixels.
