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 as a single-page web app in `index.html`. Let me plan the implementation: 1. Full-screen canvas with a dark background 2. Click handling to launch fireworks 3. Physics simulation for shells (ascent), particles (burst with gravity), and trails 4. Auto-launch on initial load 5. Clear button 6. Handle resize Let me write the complete HTML file with inline CSS and JavaScript.

File written. Now let me open it in the browser and verify the behavior.

The initial render shows a black screen with "Click anywhere to launch fireworks" text and a "Clear" button. I need to verify that: 1. A demonstration shell launches automatically on load 2. Clicking launches shells 3. Shells explode into particles 4. Clear works The canvas appears completely black - no demo shell is visible yet. Let me check the code and fix the demo launch. The issue might be timing - the demo launch happens immediately but maybe the canvas isn't ready, or the demo shell's lifecycle is too fast. Let me read and fix the code.
The demo shell isn't visible — the canvas is fully black. Let me inspect and fix the code. <tool_call> ### - read
