/*
 * The coin flip board.
 *
 * Every game is a card with two seats facing each other: the player who
 * started it on the left, the seat you can take on the right, and the coin
 * turning between them once both are filled. That shape is the convention for
 * this game and a player arriving from anywhere else already knows how to read
 * it, which is worth more than any arrangement of my own.
 *
 * A card that has just been decided keeps its result for a few seconds: the
 * winning seat lit with what it took, the losing seat dimmed with what it put
 * in. Then it leaves the board.
