DOCX: paragraph shading (w:shd) is not rendered

[developer0hye]

Summary

Paragraph shading (w:shd in w:pPr) is not rendered. Shaded monospace code blocks in the CLI-manual fixture (05_technical_manual_en.docx) lose their light-gray background (w:fill="F4F4F4"), so code is indistinguishable from body text background.

Reproduction

Convert a DOCX containing:

<w:pPr><w:shd w:val="clear" w:fill="F4F4F4"/></w:pPr>

and compare with a Microsoft Word PDF export.

Expected

The paragraph's text area is filled with the shading color across the full paragraph width, as Word prints it.

Actual

The paragraph renders on a plain white background.

Visual comparison

Ground truth (native Microsoft Office export) is on the left; office2pdf output at filing time is on the right. Both pages were rendered with pdftoppm at 150 DPI.

Resolution note: fixed by #382 via developer0hye/docx-rs#2 — paragraph-level w:shd is parsed and painted on the full-width block wrapper. Verified against Word GT at 150 DPI: all four code blocks in the CLI-manual fixture carry the light-gray background.
