+# Frontmatter Only Document
+
+This document only has frontmatter, no tailmatter. The content should be extracted without the frontmatter block.
+
+This is a simple paragraph for testing. It has exactly twelve words for counting purposes.
+
+## Simple Section
+
+Another paragraph here. This helps test the content extraction when only frontmatter is present.
