The band draws no bottom edge and no page asks it to, so `barBorder` goes with it —
a page that needs the separation draws its own line, as the detail pages now do above
the run form and the tab strip. With nothing toggling a border, the band is a flat
44px on every route.
The detached sidebar's card is a hover affordance, so it leaves when the pointer does:
off the handle and off the card both, on the same debounce a hover menu uses, because
the two do not touch and the leave of one fires before the enter of the other. The
mobile drawer is opened deliberately and still stays until it is dismissed.
