An empty first master page was swallowed by the next one's match, so the
watermark and the fold marks missed the first section entirely.
Every master of a section now writes the running zone, blank where its own
page has none — the layout takes the band off the margin for the whole
section, and an opening page lost 0.8cm of its own.
Both importers compared whether a run underlines, not how, so a red or wavy
line under a plainly underlining style came back plain.
