+# **what?**
+# Reusable workflow to check for changes in specific paths.

+# **why?**
+# Provide a single source of truth for checking which components have changed.
+
+# **when?**
+# This workflow is called by other workflows that need to know which components
+# have been modified in a PR or push.
