Methodology
Quartiles use linear interpolation across the 30 team-aggregate values (matches numpy's default percentile()). σ is population standard deviation, not sample.

Outlier z-scores use that same population σ. A z above 1.5 is notable; above 2.0 the team is genuinely tail-end on that metric.

For the lower-is-better metrics (wERA, xRA), the outlier panel sorts ascending so the strongest run-prevention staffs sit in the top three.

Team aggregates roll up every per-player game row into a single team-level row before running the same sabermetric pipeline a player gets — so this is "team-quality on the WAR scale," not "sum of player WARs." Roster-WAR sum will not match the team WAR figure.
