Cracks the DIV-BIZ2 binary format (BGF/BMF) using Division's own reader source (DPL3/BIZREAD.C) as reference: block stream, 14 vertex layouts, pmesh/strip connectivity, LOD nesting, embedded materials. Adds SVT raw-texture decoding, 1995-dialect VGF support (implicit CONNECTION_LIST, header SCALE), and a whole-drive scene audit. 108 of 241 scenes on the Glaze drive are recoverable; 26 are curated into restoration/vwe-archive.html, a self-contained WebGL gallery: Star Trek, Hull Pressure, BattleTech (incl. the polar-map mech lineup), Red Planet's Mars-canal raceway, and the Canyon demos.
