Keep the warehouse start pad out of low obstaclesThe warehouse builds pallet stacks one body per pallet, each 0.30 m tall, and thelateral clearance check ignored anything under a metre, so a pad could be seated onthe floor inside a stack and the drone spawned already intersecting it. Clearance isnow measured against the collision engine over the volume the drone occupies, thevictim is treated as an obstacle rather than an exemption, and a placement that findsno clear spot fails explicitly instead of using a known-blocked one.
