-- A design can volunteer itself for parts-only sales, the jobs made without
-- a vehicle. Nullable, so every existing design
-- keeps printing only where it was chosen. One design per rule per workshop
-- and document; Postgres treats nulls as distinct, so designs without a rule
-- do not collide.
