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.

The Gray-Scott reaction-diffusion simulation is now running. Here's a summary of the verified behaviors: ### Verified Functionality: 1. **Initial State**: - The simulation starts with a central seed of `V` and reduced `U`, visible as a distinct circular region in the center of the canvas. 2. **Simulation Evolution**: - The simulation evolves over time, showing organic pattern formation as expected from the Gray-Scott model. 3. **Pointer Interaction**: - Clicking or dragging on the canvas adds a new seed (increases `V` and reduces `U` locally), which affects subsequent frames. 4. **Pause/Resume**: - The "Pause" button stops the simulation, and "Resume" restarts it. The simulation state remains consistent during pauses. 5. **Reset**: - The "Reset" button restores the initial state with the central seed, matching the initial scene. ### Observations: - The color mapping is effective, with the central seed and added seeds clearly visible against the background. - The simulation remains responsive during interaction, allowing for real-time seeding. ### Unverified Details: - **Long-term Stability**: The simulation's long-term behavior (e.g., stability of patterns) was not fully inspected due to time constraints. - **Edge Cases**: Extreme interactions (e.g., rapid seeding) were not thoroughly tested. The simulation meets the core requirements and behaves as expected for the given task.
