## Note for browser/AI builders
Three.js runs most AI-made browser games right now, and Phaser leads for 2D. Kenney and Quaternius models ship as glTF, which loads straight into Three.js (GLTFLoader), Godot, Unity (via glTFast) and Unreal (built-in glTF import).

## Prompt tip for your AI coding agent
