I have created and saved the complete, self-contained HTML file `index.html`. It features a full-screen canvas with animated fireworks that launch on clicks, explode into particles affected by gravity, and fade over time. You can open this file in a browser to see the fireworks display in action.

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.

EVALUATION

3/5 working

Auto-launching green fireworks bursts with gravity fade; monochrome and click-to-launch not clearly distinguishable from autoplay.

Vision grade · anthropic/claude-sonnet-5

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.
