## Web (WASM + WebGPU)

Thirteen now has an `__EMSCRIPTEN__` backend that uses WebGPU in the browser.

### Build Simple example for web

```bash
emcc Examples/Simple/main.cpp -std=c++17 -I. \
--use-port=emdawnwebgpu \
-sASYNCIFY \
-sALLOW_MEMORY_GROWTH=1 \
-o simple.html
```

Then run a local web server and open `simple.html` in a WebGPU-enabled browser.

### Notes
- The web backend expects a `<canvas id="canvas"></canvas>` in the generated page.
- `SetFullscreen()` is currently a no-op on web.
- Input uses browser events mapped into the same `GetKey()` / mouse APIs.

## API Reference

#### `uint8* Init(uint32 width = 1024, uint32 height = 768, bool fullscreen = false)`
