proto: first liminal fixtures - flat field + monolith, periodic hills, raised road in fog (L141)
Standalone only: fixtures, liminal_road_override (fillDais), --audit-liminal-road-walk, capture-only distance fog. Road 65 m x 6 m, 22 m up, capsule walk 127/127. Owner hashes unchanged (v227), fast tier, Clang/GCC green. Hills repeat every 80 m but the capture reaches 56 m, so only one rise shows. Also R48 (who owns the tunnel mouth): recommends a bounded joint plan of passage ports and layer landing candidates.
