+//! Regression test for https://github.com/kreuzberg-dev/kreuzberg/issues/781
+//!
+//! DOCX OCR extraction was failing because the pipeline was deriving the document
+//! (Markdown/Text generation) BEFORE running OCR on embedded images. As a result,
+//! the renderers could not see or inject the OCR text results.
+//!
+//! This test verifies that OCR results for images in a DOCX file are successfully
+//! injected into the final content.
