Carry TerrainTex.TexTiling through the terrain atlas and upload a layer-indexed table to the modern bindless shader so base, overlay, and road textures repeat at retail scale. Keep alpha masks cell-scaled and preserve retail's verified source-level-zero high-detail selection.
Add the named-retail pseudocode, WorldBuilder/ACE/ACME cross-reference, adapter conformance tests, and inventory documentation so a future renderer migration keeps the contract.
