name: Nightly

# Scheduled nightly artifact build. This used to run on every push to main,
# rebuilding five release targets per merge; PR CI already builds/tests the
# same commits on macOS/Windows and CNB covers Linux, so a daily cadence
# keeps the artifact stream fresh without burning ~28 runner-minutes per
# merge. Use workflow_dispatch for an on-demand build.
