# Build + unit tests on every PR and on main. Pair with branch protection:
# Settings → Branches → Add rule for `main` → require this check, require PR.
# Do not pass CODE_SIGNING_ALLOWED=NO — macOS test bundles need ad-hoc signing to launch.
#
# Site-only pushes (changes exclusively under site/) skip the Xcode and SPM
# build steps but still complete green so the required "macos" check passes.
