election_title: "Abstentions — blank and abstaining ballots in STAR"

scenario_description: |-
  Six ballots tabulated, only three of which can decide the runoff: the 5-5
  Equal Support ballot, the all-zero ballot, and the truly blank ballot all
  express no preference between the finalists. Teaches the runoff
  denominator: the two-line summary (show_runoff_percent) counts ALL
  tabulated ballots and folds every no-preference ballot — the blank
  included — into one Equal Support bucket, so it reads 3 of 6 (3 Equal
  Support); the cast-vs-abstained split is carried separately by the
  abstention Note (1 of 6 ballots). Dog beats Cat 2-1 among voters WITH a
  preference, and the percentages never look like votes went missing.
