• The PR title mentions excluding only .github/workflows, but the trigger path filter excludes all .github/**. If the intent is to only skip builds for workflow changes, narrow this to .github/workflows/** (and keep other .github changes triggering builds).

  paths:
    exclude:
      - .github/**
      - .gitignore
