TableGuard, BottomSpacer, FirstPageHeader and PageChrome implement the verified pagination rules; renderCore returns bytes, a normalised layout tree, audit issues and a layout fingerprint. auditLayout detects overlaps, ink overflow, truncation, header-only pages and split blocks. Quirk tests pin the react-pdf behaviours the design depends on, and a child-process test pins the page-level absolute Svg hang.
