2// the toy factory's block machine, front +z toward the belt: a round-cornered cabinet with a striped turntable
3// on top where a tower of wooden toy blocks grows, a little robot arm on a pedestal at the back (a round head
4// with a face and a two-finger gripper holding the roof block), and a feeder column of spare blocks at the back
5// left. A railed chute (part `chute`, toys leave near (0, .75, .95)) runs off the front edge. One gene, scheme,
6// picks the colourway: seeds 1/2/3 = cobalt, sky, silver. Idle: the turntable rim spins, the arm breathes and
7// looks about, the beacon pulses. work (1.6 s): the arm lowers the roof onto the tower and lets go, the finished
8// tower slides off down the chute with a sparkle, and a fresh base block and roof pop back in
