One world, five looks, no imported assets

Leon Lin's world has a keyboard for a style guide. Keys 1 through 5 switch Natural, Painterly, Anime, Cartoon, and Ultra. Claude Opus 5.5 built the whole thing. The post is blunt about the constraint: everything is generated in code, and no asset was used.

Style switches are easy when they are color grades. They are hard when the geometry, the shading, and the outlines all change their mind together and still describe the same place. A painterly pass that destroys the street is a different town.

No imported assets makes the keypress honest. There is no model underneath wearing five costumes. The costumes are the model.
