Done. `/tmp/ws/index.html` is a self-contained Mandelbrot viewer: - **Full-screen canvas** with smooth iteration-count coloring (cosine palette, Inigo Quilez) - **Click & drag** to pan - **Mouse wheel** zooms toward the cursor - **Double-click** resets to the default view - **Resize** aware — re-renders on window resize - **Throttled rendering** via `requestAnimationFrame` so panning stays smooth - Zero external dependencies — runs entirely sandboxed

EVALUATION
Mandelbrot renders with color gradient; drag pans and wheel zooms correctly, but color scheme (green/orange/pink) is garish.

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.
