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.

The user wants me to create 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 I'll create a self-contained HTML file with CSS and JavaScript. Let me build this step by step. The Mandelbrot set is computed by iterating the formula z = z² + c for each pixel, where c is the complex number corresponding to that pixel's position. The "smooth coloring" technique uses the escape time algorithm with continuous potential/smooth iteration count. Let me write this file.

I've created the Mandelbrot set renderer. Let me verify the file exists and maybe check for any syntax errors.

The file is created. Let me verify the HTML is well-formed by checking for any obvious syntax issues.
The Mandelbrot set renderer is complete at `/tmp/ws/index.html`. **Features:** - **Full-screen canvas** - Automatically resizes to fill the browser window - **Smooth color gradient** - Uses continuous potential algorithm for seamless coloring between iterations, with a multi-sine wave palette - **Click-and-drag to pan** - Click anywhere and drag to move around the fractal - **Mouse-wheel to zoom** - Scroll up to zoom in, scroll down to zoom out; zooms toward cursor position - **Dynamic iteration count** - Increases detail at higher zoom levels - **Info display** - Shows current zoom level in the corner The renderer uses the standard escape-time algorithm with smooth coloring (continuous iteration count) for those beautiful, gradient bands instead of the stepped bands you'd get with basic coloring.
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.
RUN
EVALUATION
Colorful Mandelbrot set renders with smooth gradient; drag pans and wheel zooms correctly, no self-animation or keyboard response.

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.
