seat count

also called number of seats

How many people a seat seats, as a numeral with the dimensionless 'seater' count-unit — a single chair is a 1-seater, a loveseat a 2-seater, a sofa a 3-seater, a sectional a 5-seater. Carried by every Seat: a chair (seat_count=1), a loveseat (=2) and a sofa (=3) are ONE Seat kind differing by this VALUE, not separate kinds — seat_count 1-vs-many is a value restriction (the AA-vs-AAA battery case, the b96 Sneaker fold discipline), so Chair and Sofa do NOT mint as separate classes. Modelled as a numeral count, not a token (1/2/3/5 are values of a count, not structural categories). Reuses SeatCountUnits. Concern measurement, axis-eligible (a 2- vs 3-seater is a genuine buy choice).
