Bar: flush with the plate, not recessed

The menubar band was a plateau one step down from the root plate, carved
with a single bottom wall facing the content — paint inherited from the
retired MenuBar. Drop the carve: the bar now shares the plate's face with
the content below it, and its widgets are the only thing marking the band.
