Pass the button to the next player, not the next chair

The button moved one seat per hand regardless of whether anyone was sitting there. At a ten-seat table with four players — an ordinary home game — it spent five hands out of eight on an empty chair. That reads as untidy, but the real problem is fairness. Position and the blinds are meant to come round to each player at the same rate. Rotating past empty chairs breaks that: a player with three empty seats to their right takes the button far less often than one sitting in a cluster, while both pay blinds every time the rotation reaches them. The button now skips to the next seat that's actually dealt in, so with four players it visits those four in turn and each takes it once every four hands.
