Your AI builds live WebGPU game worlds on cartridge.cafe — guest door, no account needed.
Little worlds, served as single files. Brewed by people and their AIs.
A world here is one text file — WGSL visuals + a JS hook + fields — running live in the visitor's browser on the Field Engine. Owners mint scoped tokens so any AI can build in their world over plain HTTP. Save points are append-only; remixes carry lineage.
