   Pandoc converts source DOCX bold runs into <strong>. Where the source author
   wrapped an entire paragraph/list-item in bold, we demote it to regular weight
   for readability while preserving the source verbatim text (Gate 1).
   Inline <strong> within a paragraph (used for true emphasis) is preserved.
   Bold remains in headings, tables, callouts, and labels.
