The 1 GiB array limit counted wire bytes, but arrays are kept as f64/i64, so boolean arrays grew 8x and 32-bit arrays 2x past it, and nothing bounded the total across arrays. Every Model linked to a Geometry also built its own copy of the mesh. - A per-import Budget (2 GiB) is charged 8 bytes per array element before the array is decompressed or widened, ASCII files are charged for their parsed values, and each built mesh is charged for its vertex and index data. Going past it fails the import with a clear error instead of an allocation abort. parse_within/read_within take a lower limit for tests. - Models instancing the same geometry with the same materials share one mesh; a different material mapping still gets its own.
