## Printer Checks

- Upload the interior PDF to the printer portal and review every page in the portal preview.
- Confirm gutter, page count, spine width, paper type, cover template, and binding type before ordering a proof.
- Review PRINT_LAYOUT_AUTOMATION.md, print_layout_plan.json, print_proofing_report.json, and ebook_resilience_lab_report.json for automatic margin, folio, running-head, scene-break, runt, overlay, EPUB viewport, dark-mode, font-override, and rendered-page proof diagnostics.
- Generate separate cover templates for paperback and hardcover through the printer's own calculator; hardcover case wrap dimensions are not interchangeable with paperback covers.
- Order a physical proof before any large print run.
