This is a whole lot of nothing right now, just stubbing out some control flow that ultimately just leads to TODOs that cause it to do nothing at all. My intent here is to get this cross-cutting skeleton in place and thus make it easier for us to collaborate on adding the meat to it, so that it's more likely we can work on different parts separately and still get a result that tessellates.
