   Before this, the chat window was a mobile bottom sheet pinned bottom-right at a
   fixed width, so on a desktop viewport it sat ON TOP of the card table. Now:
     < 1150px : chat + jukebox are full-width bottom sheets (never side by side
                with the table, so nothing can overlap it); one open at a time.
     >= 1150px: the centered column (scores, table, bottom bar) shifts left by half
                a rail width; sheet.css docks the Marta/Hoyt sheet in that rail using
                the variables set here.
