File written, will verify and summarize.
Created `/tmp/ws/index.html` — a self-contained Mandelbrot set renderer with: - **Smooth gradient coloring** using the continuous iteration count algorithm (log-log smoothing) with an HSL rainbow palette - **Full-screen canvas** with no external dependencies - **Click-and-drag panning** (mouse and touch) - **Mouse-wheel zoom** that zooms toward the cursor position - **Pinch-to-zoom** for touch devices - **Adaptive iteration count** (increases with zoom level, up to 2000) - **Double-click** to reset view - HUD showing center coordinates, zoom level, and max iterations
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 with smooth gradient coloring; drag pans and wheel zooms correctly, click/keys don't affect it 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.
