standalone: landing plate removed; passage shaft rings reduced with the rock detail kept

- AddLanding no longer adds a shallow positive ellipsoid (floor plate check 71.3% -> 0%).
- Round 10 had removed all relief on passage walls to pass the ring check (smooth tube; rejected).
  Cause found instead: the owner roughness's 8-voxel Z anchors with linear interpolation. Passage-
  controlled walls now use 2-voxel anchors, blended smoothly into the 8-voxel ones.
- Ring gate (lag-20 correlation) 0.376 -> 0.038 AND shaft relief RMS 1.294 (smooth-tube control
  0.276 fails); passage/cave relief ratio 1.152. Faint rings remain deep in the shaft.
- Whole view 0.984 s cold @8w (interleaved, full payload); W1/W8 44/44 hash fields equal; routes
  5642/5642; look and far-survival audits pass; bad-shell control fails.
