I'm building a self-contained HTML file that renders the Mandelbrot set with interactive pan and zoom controls.

Created `index.html` — a self-contained Mandelbrot explorer. Features: - **Full-screen canvas** that resizes with the window - **Smooth coloring** via fractional escape-count (normalized iteration count) mapped through a cyclic gradient palette - **Click-and-drag to pan** (cursor changes to grab/grabbing) - **Mouse-wheel to zoom** toward the cursor position - **Adaptive iteration count** that increases as you zoom deeper - Uses `requestAnimationFrame` throttling for smooth interaction - No external resources or network requests Open it in any browser to explore.
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 blue gradient; drag pans and wheel zooms correctly, click/keys 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.
