Render the Mandelbrot set with a smooth color gradient on a full-screen canvas, with click-and-drag to pan and mouse-wheel to zoom.
thinking
The user wants a single-page web app that renders the Mandelbrot set with: 1. Smooth color gradient 2. Full-screen canvas 3. Click-and-drag to pan 4. Mouse-wheel to zoom Let me write this as a self-contained HTML file with inline CSS and JS.

thinking
The file has been written successfully. Let me verify it exists and looks correct.
Done. The file `/tmp/ws/index.html` is a self-contained single-page web app with: - **Mandelbrot set** rendered on a full-screen `<canvas>` using the escape-time algorithm - **Smooth coloring** via a precomputed 1024-stop palette with interpolation based on the smoothed (fractional) iteration count - **Click-and-drag panning** — offsets the complex-plane center coordinates - **Mouse-wheel zoom** — zooms toward the cursor position (and touch-pinch zoom on mobile) - **Chunked rendering** via `requestAnimationFrame` slices so the UI stays responsive during draws - A small fixed HUD showing the controls Just open `index.html` in any browser — no network requests, no external dependencies.
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 correctly with blue gradient, drag pans slightly, but wheel zoom and click show no visible change; image is very dark overall.

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.
