Generate a large medieval fantasy castle in Minecraft. The castle is made entirely of mud bricks with black slate roofs. It features multiple cylindrical towers with conical spires, connected by high walls with battlements. Include a central keep with taller towers, arched gates, stone staircases leading to battlements, and decorative banners hanging from walls and towers. The castle should be symmetrical, fully enclosed, and designed to fit together correctly from all sides. Do not include any terrain, mountains, or trees — only the castle structure itself. Provide the output as a Minecraft schematic compatible with WorldEdit or Litematica.
