//! 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.
