scenario_description: |-
  A 10-voter STAR election built for the FAQ. Berry is the consensus candidate —
  broadly liked, so Berry wins the Scoring Round on total stars. But more voters
  strictly prefer Almond head-to-head, so Almond wins the Automatic Runoff: a
  clean Runoff Reversal that shows why the second step exists. One voter scores
  both finalists 5 (Equal Support) — counted, but expressing no preference between
  the two, so it lands in neither finalist's runoff column.

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

[Condorcet Loser]
  Condorcet Loser: Cocoa — loses every head-to-head matchup

[Divergence from STAR]
  STAR     = Almond
  Approval = Berry   (differs from STAR)

[Runoff Reversal]
 - Score Round Winner(s) = (Berry)
 - Runoff Round Winner   = (Almond)
  Candidate Berry earned the highest total score, but
  Candidate Almond won the automatic runoff — not a malfunction,
  STAR working as designed: the runoff elects the finalist preferred
  by the majority (of voters with a preference).
