**Developing Single HTML** I am focusing on building a unified `index.html` file. My current priority is establishing the foundational HTML structure before I integrate the necessary CSS and JavaScript for the Gray-Scott reaction-diffusion simulation. **Structuring Unified HTML** I am currently focused on establishing the core HTML for a single `index.html` file. My immediate goal is to get the basic canvas element in place, which will serve as the foundation for the reaction-diffusion simulation before I dive into the styling and dynamic behavior. **Building Unified HTML** I am now focused on constructing the `index.html` file. My current effort centers on defining the initial HTML structure and integrating the CSS to ensure the canvas occupies the full viewport. This sets the stage for the simulation's core logic.

**Creating Gray-Scott Simulation** I've successfully set up the `index.html` file. This includes the core HTML structure, a full-screen canvas with basic CSS styling, and the JavaScript logic. I've initialized the canvas scaling (`pixelScale`) and defined the essential Gray-Scott parameters. **Refining Reaction-Diffusion Parameters** I've refined the Gray-Scott parameters and implemented a more robust color mapping. The simulation now displays more distinct and visually appealing Turing patterns on the canvas. I'm focusing on tweaking the constants to achieve specific, emergent structures.
The Gray-Scott reaction-diffusion simulation has been successfully implemented in `index.html`. You can open this file in a web browser to see the organic Turing patterns evolve and interact with them using 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.
RUN
EVALUATION
Reaction-diffusion Turing patterns animate continuously; mouse/keyboard inputs produce minimal visible seeding change.

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.
