    No completed circuit banked (best_result empty); design is a steel-twister with chain-lift climb, banked turns, and loop section—excitement untested because the loop didn't close to (60,60) facing +y within time. Building a closed steel twister is feasible but requires precise turn geometry to match start exactly.
