election_title: "Bloc STAR baseline — 3 candidates, 2 seats (clean, no tiebreak)"

scenario_description: |-
  The smallest Bloc STAR election that actually decides something: 3 candidates,
  2 seats, so exactly one candidate is excluded. (A 2-candidate / 2-seat race
  would be a non-election — both win no matter how anyone votes.)

  Bloc STAR fills seats by running single-winner STAR once per seat: elect a
  winner, remove them, re-run on the same ballots.
    - Seat 1: score all three. Alice (14) and Bruno (12) are the top two and
      advance; in the runoff Alice is preferred 2-1, so Alice takes seat 1.
    - Seat 2: remove Alice and re-run on the remaining two. Bruno (12) beats
      Clara (3) in the runoff 3-0 and takes seat 2.
  Clara (total 3) is excluded. Both seats are decided cleanly by the ballots —
  no rung of the tie-break ladder is ever consulted. This is the control the
  Bloc tie probes vary from. Bloc is majoritarian: a cohesive majority can take
  every seat.
