/* ==========================================================================
   The phone
   ==========================================================================
   Below 900px this stops being a desktop console with smaller margins and
   becomes an app: a bottom tab bar for the four screens a working day touches,
   the sidebar as a full-height More sheet, and the drawer and modal as bottom
   sheets, which is the gesture a phone user already expects.

   Everything stays reachable. A billing console has wide tables and no amount
   of layout makes a thirty-column sales register comfortable on a 390px
   screen, so those scroll inside their own container with the first column
   pinned, rather than being hidden or reflowed into something that no longer
   reconciles.
