Got it. Here is the complete 13-section spec for a niche-specific sourdough baking journal optimized for KDP. === LOW-CONTENT BOOK CONCEPT === A 120-page sourdough log built around the actual variables home bakers obsess over: hydration ratio, fermentation time, crumb-photo, and crust score. The shelf-hook: a 3-column hydration tracker that no other top-20 "bread journal" carries. === TARGET BUYER / USE CASE === Buyer: home baker, 35-55, started sourdough during 2020, follows King Arthur's Maurizio on Instagram, owns a kitchen scale and a Dutch oven, has tried two prior bread journals that "felt generic". Use cases: kitchen-counter logging, results review on Saturday, gifting to a fellow hobby baker. Gifting: Mother's Day, Father's Day, retirement, "Just bought their first dutch oven". === KDP TITLE + SUBTITLE === Title: "The Sourdough Baker's Log" Subtitle: "120-Entry Notebook to Track Hydration, Fermentation Time, Crumb Score and Photos — for Home Bakers" === 7 KDP KEYWORDS === 1. sourdough journal | 2. bread baking notebook | 3. hydration tracker bread | 4. fermentation log book | 5. home baker logbook | 6. gift for sourdough baker | 7. artisan bread journal [Continues with all 13 sections — full interior breakdown, entry-page template, cover concept, KDP description (1200 chars), Midjourney prompts, 14-day AMS launch plan at $10/day, print checklist, copyright safety notes]
