Each player's rating starts at 1500 and updates transactionally with every finished match: a team's rating is the mean of its two members and the standard K=32 formula decides the zero-sum delta applied to both members of a team. Ratings are per game type in a new player_rating table; match_player records each match's elo_delta. - GET /api/leaderboard exposes elo and sorts by it - GET /api/me/matches includes per-player elo deltas - new GET /api/me/ratings returns the caller's rating per game type - frontend: Elo column on the leaderboard, per-match delta in the history page, current rating in the lobby - python -m tavolo.backfill_elo recomputes all ratings from the recorded match history (one-off backfill for existing matches)
