Build a Gray-Scott reaction-diffusion simulation on a canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Maintain two chemical concentration fields, U and V, with diffusion and the Gray-Scott reaction, feed, and removal terms. Evolve these fields rather than displaying a prerecorded pattern. - Use a square simulation grid with wrapping boundaries. Choose stable time and spatial steps with parameters Du = 0.16, Dv = 0.08, feed = 0.035, and kill = 0.062 in simulation units. - Initially fill the field with U = 1 and V = 0, then seed a small central region with V and reduced U. Map concentrations to contrasting colors so evolving organic patterns are visible. - Clicking or dragging adds V and reduces U near the pointer. Provide Pause/Resume and Reset; Reset restores the initial fields and seed. - Choose Canvas 2D or WebGL, and bound grid resolution and work per frame to keep interaction responsive. Verify: Sample early field evolution, then seed a separate region with the pointer. Check that the added region affects the following frames. Pause and resume, then reset and compare the restored central seed with the initial scene.

I've created a Gray-Scott reaction-diffusion simulation in a single `index.html` file. The simulation includes the following features: - Two chemical concentration fields, U and V, with diffusion and reaction terms. - A square simulation grid with wrapping boundaries. - Initial conditions with a central seed region. - Interactive controls to pause/resume and reset the simulation. - Pointer interaction to add V and reduce U near the pointer. I've verified the following behaviors: - The simulation initializes with the correct pattern. - Clicking or dragging adds V and reduces U near the pointer, affecting subsequent frames. - The pause and resume functionality works as expected. - The reset button restores the initial conditions. However, due to time constraints, I haven't verified the exact parameter values or the visual styling in detail. The simulation should be responsive, but the grid resolution and frame rate may vary depending on the browser and device.
