The task is: "Build a single-page web app and write it ALL into one self-contained file named index.html in the current directory: CSS in a <style> tag, JS in a <script> tag, inline — do not create se...

The workspace is empty, which is fine. I need to create index.html with a self-contained Gray-Scott reaction-diffusion simulation. The task is to create an index.html file with a self-contained Gray-Scott reaction-diffusion simulation that grows organic Turing patterns in real time, seeded by the mouse. I need to write a single HTML file with embedded CSS and JS that runs this simulation. Key parts: - HTML structure: DOCTYPE, html, head with style, body with canvas and controls, script with logic. - Simulation: Gray-Scott model with parameters A, B. - Real-time: requestAnimationFrame. - Mouse interaction: seed new growth. - No external resources. I recall the Gray-Scott model: Two chemicals U and V.

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.
RUN
EVALUATION
Gray-Scott reaction-diffusion simulation runs and evolves organic maze/spot patterns, animates on its own, though mouse seeding effect is unclear.

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.
