    "Extracted selected building features from six official GLB tiles.",
    "Converted glTF Y-up/ECEF coordinates into local east/up/south coordinates.",
    "Flattened each building base onto the game ground; simplified projected footprints for collision.",
    "Re-encoded included textures as WebP at no more than 1024 pixels per dimension.",
    "Road polygons from official LOD2 MVT; flat elevation and decorative road markings."
