A substitute takes over a player's spot. During play: slot takeover — completed results stay, the change is shown ("Anna, for Kristjan from R3"). Before the first result: choose mode slot_swap (default) or regenerate (re-pair and redraw using levels). Unknown substitute names are added to the roster automatically.
