T
Cyd 2b8ca921cb Initial full mirror of c:\VWE (source + assets + toolchain + outputs) via Git LFS 
Complete disaster-recovery snapshot: engine/game source, game data assets,
VC6 toolchain + DX SDKs, build outputs, deployed game, and _UNUSED archive.
Large binaries in Git LFS; text preserved byte-for-byte (core.autocrlf=false,
no eol attributes). See RECOVERY.md for the one-clone rebuild procedure.
