- This integration test only checks the MediaBox, so it would still pass if
CreateDocxOptionsdropped or misordered the public margin values. The internal converter tests exercise margins, but not the public path/stream mapping; add an assertion that a text or other content position changes as expected for the publicMarginsoption on both APIs.
Assert.Equal(2, CountOccurrences(pathPdf, "/MediaBox [0 0 400 500]"));
Assert.Equal(2, CountOccurrences(streamPdf, "/MediaBox [0 0 400 500]"));

Validate the effective DOCX content area.
If the effective page width or height is less than or equal to its corresponding margin sum, throw ArgumentOutOfRangeException. Apply this check after each ApplyPageLayout call, after ApplyPageLayoutOverrides when no DOCX layout exists, and after automatic header or footer margin adjustments.
RenderState.UsableWidth and continuous-layout calculations use these differences directly. Invalid values can reach PdfPage.AddImage as zero or negative dimensions, and nonpositive content heights can be used as divisors.
