   have the same constraints, so past this width the page stops being that layout scaled up and
   becomes its own composition: a top nav (no reason to dock navigation at the bottom when
   there's no thumb to reach it), a persistent filter sidebar (there's room, so it doesn't need
   to hide), and a browsing surface that actually uses the width instead of a mobile-width column
