A document had one set for all of it, taken from whichever section declared one last — so a fixture lost its letterhead entirely and page 1 got the empty header its final section asked for. A body block now carries `sectionBreak`, ordinal rather than indexed so editing cannot desync it. Import resolves Word's "Link to Previous" per reference type; export writes a set per sectPr, and on the ODF side each section past the first gets its own master page, which the block switches to. The layer picks a page's set from where pageBreaks reports the sections starting, and each section's zone reaches ride `--pb-section-reach` so a later section's letterhead makes room for itself: page 10 of a fixture was 24.9mm out, now 1.1mm. Editing still reaches section 1 only; the rest render read-only.
