games: a table of bots you have to beat to the last card

UNO, played for chips. You stake once, sit down against one to three bots,
and going out first pays the table: 2.2x heads up, 3.6x against a full house.
Anybody else going out first takes the stake. The table size is the tier,
because it is the only dial UNO has.

The bots move inside ApplyMove. A game with opponents is normally where you
reach for a socket, and the plan says solo UNO must not — so one request plays
your move and every bot turn behind it, and hands back the whole lap as a
script the felt plays in order.

The RNG is in the state rather than an argument to it: the bots choose and a
spent deck reshuffles, so the engine needs randomness mid-game, and there is no
generator alive across requests to pass in. The seed rides in the state and each
step derives its own. The game still replays exactly as it fell.

The zero value of Color is Wild, and that is the whole point of it: a wild
played with the colour field missing from the JSON must be refused, not
quietly played as a red one. It was red for an hour.

The browser never sees a bot's card — not the deck, not a hand, not the face of
a card a bot drew, which is most of the deck. Seats cross the wire as a name and
a count.

The multiples are measured, not guessed: playing the first legal card you hold
wins 43/32/27% of the time against these bots, so the tiers price that to lose
about 8% a game and leave good play worth roughly the house's edge.

PeteFX.flyNode is the throw with the chip taken out of it, so a card can be
thrown across the felt the same way. fly() is now that with a chip in it.

Not yet driven in a browser, which in this room means not yet finished.
