Claude Medieval Castle Kingdom

An interactive medieval castle kingdom built with Three.js and WebGL. The architecture, heraldry and banners express the model's self-image, with patrolling guards, villagers, an opening drawbridge and day-to-night switching. It runs from a single HTML file that opens directly in Chrome. The prompt is a long, sectioned spec that requires self-testing and fixing, which makes it useful for 3D scene showcases or comparing model capabilities.
