The prompt

“a bookshelf where the books have become a cityscape”

A whimsical wooden bookshelf where rows of books morph into a bustling miniature cityscape. Spines of books stand upright like skyscrapers with tiny windows, balconies, and architectural details, while horizontal books form streets, bridges, and multi-level rooftops. Clouds drift in the upper background above the top shelf, completing the magical urban landscape.
