# Rebuild js/vendor/imgly-background-removal-<version>/ from npm, the way the committed copy was built.
# The bundle is IMG.LY's @imgly/background-removal (AGPL-3.0) with onnxruntime-web, zod, ndarray, and
# lodash-es (MIT). Source maps carry the original source of every bundled file, and the .LEGAL.txt
# files keep each bundled package's license notice.
#
# Usage: scripts/vendor_background_removal.sh [version]   (default 1.7.0)
# The model and WASM files are not vendored: the library fetches them from IMG.LY's servers for its
# own version. After changing the version, update the "library" path in scripts/tool_content.py.
