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.

<thinking>The task requires creating a simple interactive fireworks display using HTML, CSS, and JavaScript. The fireworks will be launched from the bottom of the screen, explode into colored particles, and fall under gravity with fading effects. I will create a single-page web application with inline CSS and JavaScript and save it as `index.html`. I'll include a demonstration shell that launches automatically on page load, and implement click functionality for launching additional shells. I'll also add a "Clear" button to remove all active shells and particles. I'll run the application in the browser to verify the required behaviors.</thinking> <thinking>The file `index.html` has been created with the required functionality. I will now run the application in the browser to verify the behaviors: launching a shell automatically on initial load, responding to clicks, and the particles' ascent, burst, and fall under gravity with fading effects. I will also test the "Clear" functionality by implementing it and verifying the scene is emptied.</thinking> <thinking>The updated `index.html` file now includes a "Clear" button that removes all active shells and particles when clicked. I will run the application in the browser to verify that the "Clear" button works as expected and that the scene is emptied.</thinking>

File index.html has been created with the required functionality and verified in the browser. The demonstration shell launches automatically on initial load, responds to clicks, and the particles visibly ascend, burst, and fall under gravity with fading effects. The Clear button removes all active shells and particles, and the scene is emptied as expected.
