Markdown autosaves to this book. Phase D1 publishes as a NIP-23 article.

0 pages · 0 reflow
Click a designed-page tile to edit it on the canvas. Click a chapter tile to edit its markdown. Per-page Nostr publish (per-event sidecars + manifest) lands in Phase D1.
The cover spread reflows automatically when page count or paper thickness changes (spine width re-derives) and when trim or bleed changes in Document settings. Editing the cover layers mounts the cover designer in Phase B; publishing the cover as its own casewrap-page event lands in Phase D1.

Ready to publish?
Double-check the details below before posting to Nostr. You can edit or delete later, but the original event will exist on relays.
Visibility
Private designs are encrypted — relays and other people can't read the contents. The event still reveals that you published something, and when. Encryption can't undo a past public publish.
Master pages
Masters are reusable page templates — running headers, page numbers, margin guides, background art. Pages that inherit a master render its layers underneath their own. The default master is applied to new pages automatically; per-page overrides come from the Pages overview.
Document settings
Trim, bleed, paper thickness, and page-numbering rules for this book. Changes apply immediately and are saved with the project.
Typography (chapter text styles)
Overrides the v1 markdown stylesheet for reflow chapters. Empty fields fall back to defaults.
