**Planning index.html creation** I need to create an index.html file and inspect the directory, though it might not be necessary. I want to make it polished, with a fullscreen canvas that is responsive and has a smooth gradient and interactions. Maybe I should consider using a performance worker? It’ll be a single file with JavaScript rendering per pixel for the gradient. Ensuring Device Pixel Ratio is important, and I need to think about drag and animation rendering, possibly using requestAnimationFrame for smoothness. I'll focus on Mandelbrot smooth coloring and palette interpolation as well.

EVALUATION
Smooth-colored Mandelbrot set renders nicely; drag pans and wheel zooms correctly, keyboard has no effect (as expected, not required).

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.
