Prompt for this run
Build an interactive fireworks display on a full-screen canvas. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. No third-party libraries are provided. Required behavior: - Clicking the sky launches a visible shell upward from the bottom of the scene toward the clicked location. The shell then explodes into a radial burst of colored particles. - Burst particles fall under gravity, fade over time, and are removed after their lifetime. Support several overlapping shells and bursts. - Launch one demonstration shell automatically on initial load so the effect is visible before interaction; subsequent shells respond to clicks. - Provide Clear to remove active shells, particles, and trails. Keep controls usable after resizing. - Use procedural drawing only. Choose the visual design, palette, and trails freely while keeping the launch-to-burst sequence visible. Verify: Trigger a shell at a chosen location and sample its ascent, burst, and early particle fall. Check that the click affects the launch target and that particles visibly spread and fade. Use Clear and confirm the scene is emptied.

The user wants me to build an interactive fireworks display in a single HTML file. Let me create a complete, self-contained file with: 1. HTML structure with a full-screen canvas 2. CSS for styling (no external resources) 3. JavaScript for: - Fireworks physics (shells, bursts, particles) - Click handling to launch fireworks - Gravity and particle fading - Clear button functionality - Auto-launch one demonstration shell on load Let me write this file and then test it in the browser.
I'll create an interactive fireworks display with all the required functionality. Let me write the complete file and test it.

Now let me test the application by opening it in the browser. I'll check the initial state and then verify the functionality.
Now let me test the application in the browser:
{"action":"screenshot"}Frame 1, +0ms
[Browser image supplied to model]
{"console":["warning: An iframe which has both allow-scripts and allow-same-origin for its sandbox attribute can escape its sandboxing."],"dom":"Clear\nClick anywhere to launch fireworks!","images":"attached"}
thinking
The application loaded successfully. I can see: 1. Clear button in the top-left 2. Dark canvas ready for fireworks 3. Instructions text The warning about sandbox attributes is just a browser warning that doesn't affect functionality. The canvas appears empty, so let me click on it to trigger a firework and verify the visual behavior.
The app loaded successfully. I can see the Clear button and instructions. The demo firework hasn't started yet - the canvas is currently black. Let me click on the canvas to trigger a firework and verify the launch-to-burst sequence works:
