Visualizing how transformers actually attend to code — interactive demo

# Attention Visualizer for Code

Ever wondered what an LLM "sees" when reading your code?

This tool shows you the attention weights in real-time.

## Key Findings
- Models pay heavy attention to **function signatures** over implementations
- **Variable names** matter more than comments for context
- **Import statements** get disproportionate attention at inference time
- Models attend to **matching brackets/parens** almost perfectly

## Try It
```bash
git clone github.com/attention-viz/code-viz
cd code-viz && npm install && npm run dev
```

Paste any code snippet and watch the attention heatmap update live.
