The single-page web app for the Gray-Scott reaction-diffusion simulation has been created and is saved as `index.html` in the current directory. You can open this file in your browser to see the organic Turing patterns grow in real time, and you can seed new growth with your mouse.

TAKE IT TO CODE

A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
