    I'll start by setting up the ride and getting the exact piece geometry to plan a closed circuit.

    Ride created at (28,45) facing east. I have geometry for dirs 0 and 2. Let me get dir 1 geometry (for the corkscrew turnaround) and start building the station + lift hill.

    Station + lift done (14 pieces, top at z=256). Dir-1 geometry confirms the corkscrew turnaround. Now the first drop, vertical loop, and corkscrew pair.

    Loops need an up-25 slope entry — that's why the previous build used `flat_to_up_25` before each loop. Fixing that and continuing with the corkscrew turnaround and the westbound leg.

    Westbound leg complete, cursor at (35,46,112) heading west. Now the S-bends, the U-turn helix, and the final approach back to the station.

    The helix needs a banked entry — adding `flat_to_left_bank` before it, then finishing the approach.

    The train is lapping (21 laps worth of stats) but the test never finalized — likely needs different conditions. Let me look at the park and retry with a much larger tick budget.
