name: Build legal manifest

# HT-14: renders every project's legal markdown to HTML and produces
# dist/legal-manifest.json — the single canonical source HT-15's consumer backends import,
# so no one hashes/versions independently. See scripts/build-manifest.py for the actual
# logic (and why there's no PDF step); this workflow just provides the environment it needs.

      # an earlier version of this workflow — a REST API gap, not worth depending on).
