Keyboard Heatmap

This tool runs in the background while you type or game on this page. It builds a visual "Heatmap" showing your most used keys. Hotter colors (Red) = More presses.

### Use Cases * **Layout Optimization**: Moving your most used spell/skill to a closer key. * **Ergonomics**: Seeing if you over-use your pinky finger (Shift/Ctrl). * **Fun**: Just seeing what your "interaction fingerprint" looks like.
