+# This script checks the generated static site (usually from
+# Jekyll or another static site generator) for:
+#   - Broken links
+#   - Invalid HTML
+#   - Missing OpenGraph tags
+#   - Missing favicons
+#   - 4xx link errors
+#
+# HTMLProofer helps ensure the built website is clean,
+# accessible, and free of broken external/internal links.
+#
+# This version adds clear comments and formatting to make
+# it easier for contributors to understand and maintain.
