election_title: "Voting styles — a valid STAR bullet vote (3 candidates)"

scenario_description: |-
  Three legal STAR ballot styles on one ballot set: a full/expressive ballot
  using the whole 0-5 range, a ballot with equal scores, and a bullet vote
  (only one candidate scored). All are valid; bullet voting is allowed but not
  recommended — if your one pick doesn't reach the runoff, your ballot has no
  say in the final head-to-head, so you forfeit influence. Vanilla wins here
  either way.
# Voting styles — what a valid STAR ballot may look like.
# STAR lets you score each candidate 0–5 independently, so several styles are
# all legal on the same ballot set.
