The `playground/` directory contains a browser-based interactive demo of the NISPS ML engine. It's a faithful JavaScript port of nisps-core's MLP + IML, with no build step or dependencies.
- **2 inputs** (virtual joystick X/Y) mapped through a `[3, 10, 10, 14, 17]` MLP to **17 outputs** controlling a Canvas2D flow-field particle system
- **2 inputs** (virtual joystick X/Y) mapped through a `[3, 10, 10, 14, 20]` MLP to **20 outputs** controlling a Canvas2D flow-field particle system
- **Two learning modes**: Examples (set slider targets, add examples, train) and RL Feedback (thumbs up/down with exploration noise)
- **Serve statically**: `cd playground && python3 -m http.server`
- **Mobile-first**: designed for touch/foldable phone use
