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.
→ write /tmp/ws/index.html (7463 bytes)

I've created the Mandelbrot set renderer. Let me verify the file exists and maybe check for any syntax errors.
→ bash {"command":"ls -la /tmp/ws/index.html"}

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.
