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.
→ write index.html (10905 bytes)

The file has been created successfully. Let me verify it's present and complete.

The file is complete. It's a single self-contained HTML file with the Gray-Scott simulation. No external resources, fully functional, interactive with mouse/touch seeding of new patterns, real-time ad...
