GREAT WALL CHINA RIDGE FOUNDATION 100M V1 IMPORT NOTES
======================================================

Copy the GLB into ./assets/landmarks/great_wall/ and merge the manifest entry JSON into the Dual Site chunked asset manifest if desired.
This module is a terrain/foundation support piece, not a wall replacement. Place GW_Module_Straight_100m over the central footprint guide when testing ridge readability.
Use preserveScale=true. Axis is Y-up and forward is -Z. Pivot is module center at the flat central bench ground plane.
Snap center-to-center at Z increments of 100m for repeated ridge chunks.
