**Building Single HTML** I’m focusing on consolidating all components into `index.html`. My current task is establishing the fundamental HTML5 structure, which includes defining the necessary `canvas` element. **Structuring Core HTML** I'm currently establishing the foundational `index.html`, ensuring it has the basic HTML5 boilerplate and the crucial `canvas` element. My next step involves integrating the styling to make the canvas responsive.

**Creating Initial Structure** I've successfully generated the `index.html` file. It's equipped with the necessary HTML scaffolding, CSS to ensure the canvas takes up the full screen, and the core JavaScript logic for Mandelbrot set calculation and rendering. This includes the smooth HSL-based coloring and the click-to-zoom functionality. **Refining Canvas Functionality** I've implemented robust click-and-drag panning, smooth mouse wheel zooming, and responsive window resizing, ensuring a fluid user experience. The initial rendering is now complete, displaying the Mandelbrot set upon page load with dynamic calculations.
The Mandelbrot set web app has been created and saved as `index.html`.
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
Mandelbrot renders with smooth vivid gradient; drag pans and wheel zooms correctly, click/keyboard 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.
