Postseason
Every bowl, one card, filled in before the first kickoff in December and settled on New Year's Day. Scored the same way the weekly board is, over a slate that arrives all at once rather than a week at a time.
Open the bowl boardGIC projects the full bowl lineup from the season you have picked — matchups, tie-ins, and the playoff field that feeds it. What is not built yet is running that board as a contest between people rather than as one person's projection.
A competition whose `allowedGames` is the postseason slate, and a lock policy that closes the whole card at the first bowl rather than game by game.
`competitions.rules.lockPolicy` takes 'first_kickoff' for exactly this, and `allowedGames` already restricts a board to a named list of games.
