Created `/workspace/index.html` — a fully self-contained Gray-Scott reaction-diffusion simulation. Features include: - Real-time organic Turing pattern growth - Click-and-drag mouse/touch seeding - Feed rate, kill rate, growth pressure, and brush-size controls - Preset morphologies such as Coral, Maze, Worms, and Bubbles - Multiple color palettes - Pause/resume and reset controls - Live FPS, active-area, iteration, and field-state readouts - Responsive layout with no external resources or network requests Syntax check passed successfully.

EVALUATION
Gray-Scott simulation grows organically at first but eventually fills the entire canvas with solid color, losing pattern detail.
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.
