The same bar Layout has, from the same opt-in: the section says it has a preview and the controls
appear. Pages — the list — still says nothing, because there is nothing there to view at tablet width.
VIEW paints nothing at all. Not dimmed chrome or hidden buttons: no injection, so the frame holds
exactly the document the site served. That is what View has to mean here — the outlines, the labels and
the drop zone are the editor's, and a preview that keeps any of them is not showing you the page.
Done by putting `mode` in the callback's dependencies rather than by branching on it somewhere else.
Switching hands SitePreview a new function; its effect runs the previous paint's cleanup and then does
nothing. The chrome goes without a reload and without a second code path that could disagree with the
first.
