# Create or replace assets on the GitHub release for this OTP hash. Mirrors
# Step 4 of build_release.md.
#
# Inputs (env or default):
#   HASH    — release tag hash (auto-detected from $OTP_SRC git)
#   OUT_DIR — where the tarballs were written (default: /tmp)
#   REPO    — GitHub repo (default: GenericJam/mob)
#   ASSETS  — space-separated list of tarball basenames to upload. Defaults
#             to all five if all exist; otherwise only the ones present.
#
# Behaviour:
#   - Creates the release `otp-$HASH` if it doesn't exist.
#   - For each asset that's already on the release, deletes it first
#     (`gh release upload` won't replace by default).
#   - Uploads everything in one `gh release upload` call.
