Chance is disclosed, and the deck is committed
High Card is a chance game: card order, not pure skill, decides the rounds. Before cards are dealt, the server and both players commit the inputs used to make one shared 52-card deck. No fresh randomness is requested during the match.
Each round reveals one card for each player. Equal ranks burn and redraw from the same committed deck, so only a decisive pair advances the score. After five decisive rounds, the complete seed inputs and consumed deck prefix form the full proof after the match.
How the money moves
A decisive round transfers ceil(stake / 5) from the loser to the winner, capped by the loser's remaining balance. Burned tie cards transfer zero. There is no extra terminal transfer after the fifth decisive round.
