🎯 How to play: move the Surgical Levers (left) until every goal card above turns green. Watch the viewports react, scrub the healing clock, and if stuck press a ⚡ Fix button (right) to apply the textbook correction — then try to beat it with your own combination. Forces are in newtons: a truly passive released flap pulls < ~0.05 N at the margin (De Stavola 2014).
