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.

I'll create a single-page fireworks display with the required functionality.

I need to wait for the demonstration firework to appear, as it was scheduled to launch after a 500ms delay. Let me check the console and DOM again after a short wait to see if the firework has appeared.

I need to investigate why the demonstration firework isn't appearing. Let me check the console for any errors that might be preventing the animation from working properly.

I need to check if there are any JavaScript errors preventing the fireworks from displaying. Let me try to trigger a firework manually by clicking on the canvas to see if that works.

I can see that a small firework has appeared at the bottom of the canvas after clicking. This indicates that the code is working, but the demonstration firework might not be visible because it's launching from the bottom and might be too small or too faint to see immediately. Let me try clicking again to trigger another firework and see if I can observe the full effect.

I need to wait a bit longer to see if the fireworks are actually working but just taking time to become visible. Let me check the console for any errors that might be preventing the animation from working properly.

I can see that when I click on the canvas, a small dot appears at the bottom, which suggests the firework launch is working but the visual effect is very subtle. Let me try clicking again to see if I can observe the full effect.

I can see that the fireworks are launching but they're very subtle. The firework appears as a small dot at the bottom of the screen. Let me try to improve the visibility by making the firework shell larger and adding a more visible trail. I'll modify the code to make the firework shell larger and the trail more visible, and also ensure the demonstration firework is more prominent.

I've made the firework shell larger and the trail more visible. Let me reload the page to see if the demonstration firework is now more visible, and then I'll test clicking to trigger additional fireworks.

I can see that when I click on the canvas, a small red dot appears at the bottom, which suggests the firework launch is working but the visual effect is still very subtle. Let me try clicking again to see if I can observe the full effect.

I need to make the fireworks more visible. Let me modify the code to make the firework shell larger, increase the particle count, and make the particles more visible by increasing their size and adding a glow effect.
{"path":"index.html","edits":[{"oldText":" // Draw shell\n ctx.beginPath();\n ctx.arc(this.Successfully replaced 2 block(s) in index.html.
