Done. Brief summary.
Created `/workspace/index.html` — a self-contained Mandelbrot explorer: - **Smooth coloring**: large bailout radius + fractional iteration (`nu = i + 1 - log(log|z|)/log2`) fed into a cosine palette, no banding - **Pan**: click-and-drag, updated live - **Zoom**: mouse wheel anchored at the cursor point, with iteration count scaling up as you zoom in - Full-screen canvas with devicePixelRatio support, chunked rendering via `requestAnimationFrame` so the UI stays responsive, and a HUD showing center/zoom/iterations Open it directly in a browser — no dependencies or network needed.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.

EVALUATION
Mandelbrot renders with smooth gradient; drag pans and wheel zooms correctly, click/keys have no effect as expected.

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.
