scenario_description: |-
  A club presidency with two wings and one bridge-builder. Brook is scored
  3+ by every single voter and beats each rival head-to-head (5-4 over
  Avi, 6-3 over Cole) — the Condorcet winner. But Brook has only 2 first
  choices, so RCV-IRV eliminates Brook FIRST and elects the wing candidate
  Avi 5-4: the center squeeze. STAR reads the full scores instead: Brook
  tops the scoring round 31-23-18 and wins the runoff against Avi 5-4.
  A drill for the squeeze mechanism (see the center-squeeze topic pages);
  ballots and cast are this repo's own. Exercise: ex05_center_squeeze.md.
