scenario_description: |-
  The LH reference for BetterVoting test BV1815 (a real election, id fk38pk,
  marked Passed). Labeled "basic/simple", but it quietly exercises the score
  tiebreaker at the second seat.

  Bloc STAR, 3 candidates, 2 seats. Totals: A=12, B=1, C=2.
    - Seat 1: A (12) and C (2) advance; A wins the runoff 3-0, taking seat 1.
    - Seat 2: remove A -> B and C. In the runoff B and C TIE 1-1 (one voter
      prefers each; one is Equal Support). The tie falls to the SCORE rung:
      C's total (2) beats B's (1), so C takes seat 2.
  Winners: A, C. BetterVoting agrees (tieBreakType: "score", elected A, C) — this
  case Passes; it's the Bloc analog of a runoff decided by the score tiebreaker.
  (Aside: the BV export labels votingMethod "STAR" rather than "Bloc STAR" — #904.)
