election_title: Quorum — an abstention still counts toward turnout
scenario_description: |-
  A 10-member board (eligible_voters: 10). Six members submit a ballot — five
  score the candidates, and one turns in a BLANK ballot (an abstention). No
  explicit quorum is set, so the engine's default applies: a majority (>50%) of
  eligible voters must participate — i.e. at least 6 of 10.

  The teaching point (ties quorum to abstention): the blank ballot is the SIXTH
  participant. A cast abstention is still participation, so it counts toward
  quorum — and here it is exactly what carries turnout from 5 (not enough) to 6
  (quorum met). Drop the abstention and quorum would FAIL. The abstainer changed
  no candidate's score, but their presence made the election valid.
