Built `index.html` — self-contained Gray-Scott reaction-diffusion Turing pattern engine. **Features** - Real-time 256×256 double-buffered Gray-Scott solver (9-point Laplacian, feed/kill, Du/Dv) running at 2–40 steps/frame (~10k+ steps/s) - Canvas grows organic patterns continuously; renders via `putImageData` → scaled display canvas - **Mouse/touch paint**: click-drag seeds V-chemical with interpolated brush stroke — draws new colonies instantly - Presets: Maze, Mitosis, Spots, Worms, Waves, Bubbles (auto-sets F/K); live sliders for Feed/Kill/Diffusion/Brush/Speed - Play/Pause (space), Reset (R), Random splatter (C), Clear, Wrap edges, Smooth/Crisp scaling, 4 organic palettes (Biolume/Coral/Abyss/Ink), auto-wander, FPS counter, PNG save — no external resources.

RUN
EVALUATION
Gray-Scott reaction-diffusion evolves nicely from blobs to maze patterns, click/drag seed growth, space pauses correctly.
Vision grade · anthropic/claude-sonnet-5
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.
