Notes:
- First Cloud-scale full-pipeline run including season_outcome_context.
  Previous 10K full-pipeline runs only wrote game_outcome_context + PBP.
- Season context overhead: 7.08s for 1,728 rows. Projection to 100K: ~70s
  linear (season accumulator state grows with world count, write is a
  single bulk-copy at end of run).
- Sim time +30s vs non-season 10K — attributed to the lock-protected
  AmericanFootballSeasonAccumulator.AccumulateGame calls on the hot
  simulation path (288 games × 10K worlds = 2.88M locked calls).
- Peak client RAM 41.4 GB (vs 14.1 GB in the prior 10K full-pipeline
  without season). Season accumulator retains per-world outcome state
  for all worlds until the final flush — this is by design of the
  SeasonOutcomeContext (Array(Float64) of length world-count per
  outcome) but accounts for ~27 GB of the peak at 10K. At 100K it will
  be ~4× larger ≈ 12 GB of season accumulator state, still within
  container budget.
