Every chapter after the first now starts on a new page via a
Chapter_20_Break heading style (fo:break-before="page"); the first
chapter keeps the plain heading so there is no blank leading page.
Chapter titles now resolve as: manual override > "# Title:" header >
the chapter's 1-based position in the left pane (e.g. "3."). The old
"# heading" / filename fallbacks are replaced by this numbering, and the
same logic drives the chapter-title hint.
