Whole and half lines are a single bet; quarter lines split the stake equally between line - 0.25 and line + 0.25. Each part: margin = home_goals - away_goals + part_line; positive wins stake_part * price, zero refunds stake_part, negative loses. Return [total return in cents rounded down, label] where the label is win, half-win, push, half-lose or lose from the summed part outcomes.
