/**
 * A synthetic institutional donor .docx for the report-renderer tests.
 *
 * The real donor in reference/ is gitignored, so tests build a minimal
 * stand-in that exercises the same parts the renderer touches: a body whose
 * sectPr references header/footer parts, a header carrying a VML watermark
 * plus a banner image, a footer, table styles, and media. The renderer must
 * preserve every part except the body, so the fixture asserts that claim.
