Case contract

Round-robin football table. results rows are [home, home_goals, away, away_goals]. A win is 3 points, a draw 1. Rank by points, then goal difference, then goals scored, then head-to-head points among the teams still level on all three (only matches between those teams), then team name. Return rows [team, played, points, goal_difference, goals_for].

Why this case matters

League tables drive promotion, relegation and seeding; the tiebreaker cascade order matters.
