Upright Archive
Carry two upright archive cases to their labeled docks: A from the upper-left to the lower-right, B from the upper-right to the lower-left. Drive the trolley with Turn and Forward; Handle picks up or sets down a case while standing on its square. The stone thresholds across the middle row require a RAISED load when entering or leaving. The low arch at the top center requires a LOWERED load. Turning while raised tips a case unless you arm your single safety strap; the strap protects one raised turn, then is spent. Lowering before turning is safe, but costs time. Deliver both within 60 trolley actions. Selection-free named controls work on phones; restart is always available.
