# Generate SPDX 2.3 JSON for ui/ using a pinned pnpm standalone that includes `pnpm sbom`.
# Supports Linux (amd64, arm64) and macOS (Intel, Apple Silicon). Used locally and in
# .github/workflows/release.yaml (see --write for CI output path).
#
# CLEANUP once ui/package.json `packageManager` is pnpm 11+ and ui/pnpm-lock.yaml is refreshed (`pnpm install` in ./ui):
# - Delete this script; in .github/workflows/release.yaml use `pnpm sbom` (see comments there). The export of
# COREPACK_ENABLE_STRICT=0 below goes away with this file.
