Run a Gray-Scott reaction-diffusion simulation on a canvas that grows organic Turing patterns in real time, with the mouse seeding new growth.

I'm setting up a Gray-Scott reaction-diffusion simulation that runs in a single file.

Let me quickly validate this.
Done. `index.html` is a self-contained Gray-Scott reaction-diffusion simulation. Highlights: - **Live simulation** — full Gray-Scott two-chemical model (A/B diffuse + react each frame) computed on a downscaled grid with a weighted 9-point Laplacian and toroidal wrapping, rendered via `putImageData` for speed. - **Mouse seeding** — click/drag on the canvas injects chemical B along the stroke, spawning new organic growth in real time. - **8 presets** (Coral, Mitosis, Spots, Worms, Maze, Waves, Holes, Bubbles) plus live feed/kill sliders and steps-per-frame control. - **5 color palettes** (Aurora, Magma, Ocean, Mono, Acid). - Pause/Resume (or Spacebar), Clear, Random Seed buttons; press **H** to toggle the panel. - Auto-scales grid resolution to the window; no external resources or network calls. Open it directly in a browser to watch the patterns evolve.
