/* A poker table has one dealer button. This one drew nine.
Every seat carried a puck — the button's, and eight ghosts at 0.32 opacity that
were there to be pressed. Measured on a nine-seat table: eight pale discs, all
eight showing the letter D, one of them real. Finding the button meant comparing
nine identical shapes for the one that's gold, when it should be the only thing
of its kind on the felt. The ghosts also sat on top of their neighbours: every
remaining "something important is covered" offender on a crowded table was a
seat covered by the seat-next-door's ghost puck.
So a seat that doesn't have the button doesn't draw one. The affordance is still
there — hovering a seat fades its slot in, which is a preview of where the button
would go — and on touch, where there is no hover, "Give the button" has always
been in the seat's long-press menu. Keyboard reaches it by focus.
