  The base case: nine voters, three speakers. Ari's four fans vote
  honestly (Ari 5, Bree 3, Cash 0). Scoring round: Bree 25, Cash 21,
  Ari 20 — Bree and Cash advance, and Bree (the broad compromise) beats
  Cash 5-4 in the runoff. Ari's fans get their second choice. The
  companion file ex06_bullet_backfire.yaml reruns the SAME election with
  those four fans bullet voting (Ari 5, everyone else 0) — and hands the
  win to Cash, their nightmare. Exercise: ex06_bullet_backfire.md.

[Condorcet Winner]
  Condorcet Winner: Bree — matches the STAR winner

[Condorcet Loser]
  Condorcet Loser: Ari — loses every head-to-head matchup — elected by Choose-One (Plurality)!

[Divergence from STAR]
  STAR                   = Bree
  Choose-One (Plurality) = Ari   (differs from STAR)
  RCV-IRV                = Cash   (differs from STAR)
  Note: no ballots had tied scores, so RCV-IRV vs STAR here is a genuine
        method difference, not a tie-breaking artifact.
  Note: Ranked Robin (RCV-RR) agrees with STAR, so RCV-IRV is the lone
        outlier — the classic center-squeeze signature.
