Review Comment:
   This pattern rejects valid quoted bookmark arguments such as `REF "_Ref100" 
\h` and `PAGEREF "target"`, because the capture must begin immediately after 
whitespace. The repository's Word-field fixture 
`testRTF_nestedHyperlinkPageRef.rtf` already demonstrates quoted `PAGEREF` 
syntax; the equivalent DOCX field will therefore remain plain text. Accept 
consistently quoted or unquoted bookmark names and add a quoted DOCX case.
