Phase A4 skeleton: tiles are placeholders. Click a tile in Phase B to edit the page. Reflow / NIP-23 chapters arrive in Phase C.5; per-page Nostr publish 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.
Document settings
Trim, bleed, paper thickness, and page-numbering rules for this book. Changes apply immediately and are saved with the project.
