Usage:
  BLOB_READ_WRITE_TOKEN=<token> scripts/viewer/upload-viewer-models-catalog.sh [directory] [upload options]

Uploads the models catalog and CAD Viewer-supported assets to Vercel Blob.
The uploader excludes mechbench/, mechbench2/, 7dof_arm/, and Python source
files by default.

Environment:
  BLOB_READ_WRITE_TOKEN                     Vercel Blob read/write token.
  VIEWER_VERCEL_BLOB_READ_WRITE_TOKEN       Alternate Vercel Blob read/write token.
  VIEWER_ASSET_BACKEND                      Optional. Defaults to vercel-blob.

Blob prefix:
  models                                    Script-defined upload prefix for this branch.

Options are passed through to npm --prefix viewer run upload:blob.
If no directory is passed, models/ is uploaded.
Use --skip-existing to reuse matching remote catalog assets, and
--fetch-missing-lfs to download only the Git LFS objects needed for new or
changed uploads.
