// The hold'em table.
//
// Same bargain as every other table in the room: the browser holds no game. It
// sends one move, and what comes back is that move *and every bot action behind
// it* — plus whatever streets that finished and whatever the pot did — as a
// script of events. So a round trip here can be a whole hand: shove all-in and
// the flop, turn, river, showdown and payout all arrive in one response, and this
// file's job is to play them back slowly enough that you can watch it happen to
// you.
//
// The one thing here that no other table has is a *second seat with money on it*.
// Everywhere else the spot is a singleton, because there was only ever you and
// the house. Here every seat has its own, chips move from a seat to its spot and
// from every spot into the pot, and out of the pot to whoever won it. PeteFX.spot
// still owns the rule that the number under a pile is a readout of that pile, so
// none of that arithmetic lives in here.
//
// And the browser never learns a bot's hand. Their cards are backs until a
// showdown turns them over, because a showdown is the only time a player at a
// real table would be looking at them.
