# THROWAWAY build smoke-test for the macOS (Tart) runner. Verifies both
# *-apple-darwin targets actually compile and link (incl. arboard's AppKit)
# through the flake on the real Mac, before the full release-macos workflow is
# wired. Delete once that lands.
#
# Push-triggered (workflow_dispatch only works for workflows on the default
# branch; our CI is on `ci`). Runs when the flake/toolchain or this file change.
# Bring the Mac up before pushing so the run isn't left queued.
