the open page lists its bands in the nav

Browse Source 
A third level, under the selected page only — every page has bands, and listing
all of them would make the nav longer than the site.

Announced by the builder rather than fetched again: it already reads them to know
what it is looking at in the document, and it mounts exactly when a page is open.
Cleared on unmount, or the nav keeps listing the last page's bands.

Clicking one writes a third URL segment and the preview scrolls to it, keyed on
the render count too so the position survives a save replacing the frame.
