Stage 5 — Format: The Invisible Craft Readers Only Notice When It's Missing

Nobody ever praised a book's margins. But every reader, within seconds of opening a book, decides whether it feels real — and formatting is what they're sensing.

Two editions, built properly

Days 9–10 produce the print paperback interior — industry-standard 6×9 trim, professional typography, correct front matter, consistent chapter styling, clean page geometry — and the Kindle ebook edition, with working navigation and styling that survives every Kindle device and font setting a reader might throw at it.

Why this stage is separate

Formatting errors are the number-one tell of a self-published book done cheaply: cramped gutters, widowed lines, mystery fonts, a table of contents that links nowhere. Amazon's previewer will accept a sloppy file; readers won't. Giving production its own gated stage — after the words are locked, before the cover is built — means the interior is finished craft, not an afterthought squeezed into upload day.

By the end of Day 10, your book exists as a product. It just doesn't have a face yet. That's Stage 6.
