**Calculating with formulas** I’m looking at a formula for the continuous function, which relates to how I calculate nu. It seems that I should express nu as n + 1 minus the log of the log transformed with the square root of z values. But I wonder if using the common form will work too. I also need to generate a color palette with a length of 1024, interpolating between colors from blue to magenta. Finally, I’ll implement an interpolation function and write a file with my results.

I've created a single-file, full-screen Mandelbrot explorer: index.html. It supports click-drag panning, mouse-wheel zoom (centered on cursor), double-click to reset, and touch gestures (drag and pinch). The coloring uses a smooth palette and continuous (smooth) iteration counts for gradient transitions. Open index.html in a browser to run.

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 set with smooth gold/blue gradient renders correctly; drag pans and wheel zooms work, click/keys don't (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.
