# LOCAL FALLBACK: build Gridline for macOS on this machine and upload the signed
# + notarized DMGs to the GitHub release for a given tag.
#
# macOS is normally built, Developer-ID signed and notarized by GitHub Actions
# (.github/workflows/release.yml) using the APPLE_* repository secrets, together
# with the Windows and Linux installers. Reach for this script when you want a
# signed build without spending CI minutes, or when Actions is unavailable.
#
# Usage:
#   TAG=v0.8.1 ./scripts/release-mac.sh
#
# The release is keyed by tag: the Actions job creates the draft on a tag push,
# and this script finds it (creating it only if it somehow doesn't exist) and
# attaches/replaces the two DMGs — Gridline_<ver>_aarch64.dmg and
# Gridline_<ver>_x64.dmg. Uploads use --clobber, so a locally signed DMG
# supersedes the CI one; publish the draft afterwards on GitHub.
#
# Auth: the `gh` CLI (GitHub is the only release target; the Gitea mirror is
# code-only).
