Turbo-Frame header to the request. When that header is detected by the controller, we ensure that any template layout is skipped (since we're only working on an in-page frame, thus can skip the weight of the layout), and that the etag for the page is changed (such that a cache for a layout-less request isn't served on a normal request and vice versa).
This is merely a rendering optimization. Everything would still work just fine if we rendered everything including the layout. Turbo Frames knows how to fish out the relevant frame regardless.
