GREAT WALL CHINA MODULAR KIT MASTER V1
=======================================

This is build 10 for the Great Wall of China asset family.

Purpose:
- Consolidate builds 1 through 9 into one Dual Site-ready kit folder.
- Provide a visual showcase/index GLB and OBJ for quick import verification.
- Provide a combined manifest and master catalog for runtime/import tooling.

Important:
- The showcase GLB is a proxy/index yard. It is not the playable Great Wall.
- The actual playable/full-scale assets are the individual GLB files in assets/landmarks/great_wall/.
- The full-length reference strip remains a compressed debug/reference asset at 1:1000 length scale.
