Manage players, start rounds, and set up the team pool.
Randomly draws one team per active player, and ends any round currently running (without a winner). From there, each team's full-time goals build up across however many matchdays it takes until someone lands on exactly 11 — nothing counts until a match's final whistle. The pot itself grows automatically every week there's no winner — no need to top it up by hand.
Run this once to load real team data (and once each new season). Uses the leagues configured via the LEAGUE_IDS environment variable (default: Premier League, Championship, League One, League Two).
