Task brief
Design a small castle-style drawbridge: two short stone gatehouse pillars 4 studs apart, each 5 bricks tall, with a wooden bridge plate between them that is hinged at the bottom edge so it can swing up to close the opening. When closed, the bridge plate should cover the opening between the pillars. Output a BOM.
