    I have full geometry now. My plan: an original out-and-back design — station at (40,40) facing +x, chain lift to z=288, 60° first drop, twin vertical loops, banked turnaround, then a return leg with two corkscrew pairs, airtime hops, s-bends, and a western turnaround back into the station. That gives 6 inversions (2 loops + 4 corkscrews). Let me start building.

    The vertical loop needs an up-25 slope entry (that's why its geometry shows slope_out=6). I'll add slope transitions around each loop.

    Banked 6.43 excitement (intensity 7.03, similarity 0.37) — already better than round 1's 6.08. There's headroom (intensity limit ~10), so I'll rebuild bigger: taller lift (z=320), steeper double-60° drop, three vertical loops, two corkscrew pairs, and more airtime hops.

    7.05 banked, but intensity hit 9.26 — nearly at the 10.0 cliff, so further additions would backfire. The design has plateaued (6.43 → 6.69 → 6.95 → 7.02 → 7.05). I'll lock this in and verify my best result.
