# Cancel in-progress CI runs when a new commit arrives on the same ref.
# This prevents multiple stale runs from queuing behind each other and
# monopolising the self-hosted macOS arm64 runner.

group: ci-${{ github.ref }}

jobs:
# Detect which paths changed so downstream jobs can skip when only
# docs/markdown files were modified. Uses git diff (no Docker — works
# on macOS self-hosted runners unlike dorny/paths-filter).
# docs/markdown files were modified. Uses plain `git diff` — no macOS
# dependency, so this runs on ubuntu-latest to free the self-hosted
# macOS arm64 runner for jobs that genuinely need it.
