Everything drawing can produce, for the dispatch that runs before the kind is known. A caller
does know, and gets the one arm that applies through Drawn.
The node arm is not the mesh arm: drawing a node draws an axis triad, which is a
TransformNode and not geometry, and saying so is what lets that path return what it builds
instead of asserting it is a mesh.
