election_title: Vote splitting — two chocolates split the majority
scenario_description: |-
  Election: pick ONE dessert for the party. 360 voters.
 
  220 of the 360 are chocolate lovers — a clear 61% majority. But there are TWO
  chocolates on the menu, DarkChoco and MilkChoco, and 140 voters prefer Vanilla.
 
  Under Choose-One Plurality each voter may name only one flavor, so the
  chocolate majority splits its vote — 120 for DarkChoco, 100 for MilkChoco —
  and Vanilla wins with just 140 of 360 (38.9%), a dessert a 61% majority
  actively dislikes. That is vote splitting / the spoiler effect.
 
  STAR fixes it without asking chocolate to drop a flavor: every voter scores
  all three 0–5, so a chocolate lover can give BOTH chocolates a high score
  instead of choosing between them. The two highest totals advance to an
  automatic runoff, and the winner has majority support head-to-head.
