Collectible Miniature Diorama of a Developed Desert Oasis Settlement

A highly detailed prompt for Nano Banana Pro to generate a stylized 3D collectible miniature diorama. The scene is a developed desert oasis settlement with sandstone merchant buildings, a central trading hall, and an oasis pool. The style mandates smooth matte ceramic/resin textures, simplified geometry, and professional studio product lighting, explicitly avoiding photorealistic textures or real-world photography aesthetics.
