prosolis 8310b30439 games: a deck you can seed and a blackjack you can replay ...

The first two pieces of games.parodia.dev, both pure: no HTTP, no timers, no
euros, nothing that knows a player's name.

cards/ is the shared deck gogobee never had — blackjack carried its own, UNO
carried another, hold'em leaned on a third-party one. The RNG is threaded rather
than the package global, so a hand is reproducible from its seed. That's what
makes the engine testable, and what lets a disputed hand be dealt again exactly
as it fell.

blackjack/ is ApplyMove(state, move) -> (state, events, error), where an error
means the move was illegal and nothing else. gogobee's engine *was* the message
sender, so its errors meant "the send failed"; there was no seam to test against.
State is a plain value, so a hand survives a redeploy.

House terms match the Matrix table — six decks, 3:2, dealer hits soft 17 — plus a
5% rake. The rake comes off winnings only: a push returns the stake untouched and
a loss is never charged for the privilege.
