Level 143

Confirm these board landmarks

Block Out Level 143 is a dual-board feeder — an upper placement grid drains through a purple phase counter into a lower yellow-bordered frame whose central number ticks from `17` downward. The phase counter gates the speed: each milestone unlocks the next batch of pieces for transfer. Push the right-side blocks before the counter reaches its midpoint and the lower frame jams with pieces arriving out of order.
