# Build, package, and deploy Skald Circle for macOS (ARM64).
#
# Usage:  ./ci/package-macos.sh
#
# Behaviour depends on the current git branch:
#   release  → builds a release tarball, checks version uniqueness, uploads + updates LATEST
#   main     → builds a nightly tarball, uploads to nightly/ (no version check)
#   other    → aborts with an error
#
# Prerequisites:
#   - macOS ARM64 (Apple Silicon)
#   - SSH alias "skaldserver" configured in ~/.ssh/config pointing to the builds host
#   - ssh + scp working to skaldserver (key-based auth)
#   - ci/package.sh, ci/verify-version.sh in the repo
