**Considering project requirements** I need to create a robust, responsive design that focuses on cursor-centered zoom and smooth coloring. Implementing an overlay for controls could be useful, even if not specifically requested. I think keeping everything in one file would streamline the process. I'm also considering whether a keyboard reset function might be necessary. Okay, let's start writing this out to make it all come together!

EVALUATION
Mandelbrot set viewer responds to drag (pan) and wheel (zoom), but keyboard input has no effect.

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.
