scripts/cover.js computes the exact cover canvas dimensions from the page count in book-meta.json (written by build.js), using the KDP Premium Color spine formula (0.002347 in/page), and renders a Nunjucks template to a single PDF containing back cover, spine, and front cover with bleed (0.125 in) and safe-zone overlay guides. - `pnpm cover` — generate output/cover.pdf - `pnpm all` — build interior + both PDFs in one command - Cover artwork slots: images/cover/front.png, images/cover/back.png Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
