# Design notes:
# - Matrix parallelism cuts wall time from ~3-4min to ~60-90s (cache warm).
# - Concurrency group cancels superseded runs on the same ref (saves runner time on rapid pushes).
# - Build leg produces dist/ artifact; test leg downloads it instead of rebuilding (DRY).
# - fail-fast: false so every failure is visible in one run (no re-pushing to see the next failure).
