(in-kind, no cost to us).\n- Last year's gala lost money because of rain; this year the hall has a covered deck.\n- Kai wants to raise tickets to $95. Not decided, and the board meets after invitations go out.\n- Catering price includes service staff and the dessert table.\n- Volunteers are handling check-in and the coat room.\n- Date: Saturday, April 18, 6-10 pm.","rules":[{"type":"numberedItems","count":3},{"type":"plainText"},{"type":"maxWords","max":70}],"mistakes":[{"title":"Not mentioning the sponsor","why":"The AI counts the band, so break-even jumps to 140 guests.","fix":"Add: \"A board member pays the band.
