Blueprint Book Trade for Master Librarian Villagers

I suggest adding a Blueprint Recipe Book as a trade for Master Librarian Villagers. The book would contain 10–12 house designs, showing previews, required blocks, and exact material quantities. Players could place a transparent blueprint to see where each block belongs and follow step-by-step building instructions. Players would still collect materials and build manually. The blueprint would only guide them. This feature would help beginners build better houses and make Villager trading more useful. Future books could include castles, bridges, and farms.
