+`excluded.csv` records the assets a processing pipeline should skip: 3 that no importer reads
+cleanly (corrupt rigs, singular transforms, NaN axis limits) and 15 whose animations are

+`tpose/<stem>.png` is a 1024×1024 2×2 grid of the asset's rest pose — front and back on the
+top row, left and right below — rendered (EEVEE) from its GLB, one per asset in `glb/`.

 Filenames are unchanged, so every asset maps back to its Objaverse entry:
