Case contract

Input: {"pot", "winners", "seats" (clockwise), "button", "unit" (smallest chip in play; pot is a multiple of it)}. Split the pot equally in whole units; each leftover unit goes to one winner, starting with the first winner clockwise from the button (the button itself is last). Return {winner: amount} sorted by name.

Why this case matters

Odd-chip placement is where split pots disagree between dealers and software.

One recorded failure
