# Container documents (OOXML/ODF/EPUB zips, OLE, RTF) a plain-text write can
# NEVER produce validly: read_file auto-extracts them, so writing the text back
# via write_file/patch silently destroys the document. PDF is deliberately
# absent — raw PDF syntax is text-authorable, so only overwrites are dangerous
# (the write guard handles that via is_pdf_path).
