Create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts.
thinking
The user wants a full-screen canvas fireworks display. Clicks should launch shells that travel upward, then explode into particles with gravity and fading effects. Everything must be in one self-contained HTML file with inline CSS/JS and no external resources. Let me build this with a clean, visually appealing fireworks simulation in a single HTML file.

thinking
The file has been created. Let me verify it exists and provide a brief summary to the user.
Done! `index.html` is ready at `/workspace/index.html`. **What it does:** - Full-screen canvas with a starfield background - **Click** anywhere to launch a firework shell that arcs upward - Shells burst into **60–120 particles** with gravity, air drag, and gradual fading - Each particle leaves a short **trail** for a comet-like tail effect - Explosions have a quick **white/yellow flash** - Clicking and dragging fires a stream of shells - Occasional **ambient auto-launches** keep the sky alive - Twinkling stars in the background - Works on desktop (click/drag) and mobile (touch) Everything — CSS, JS, canvas rendering — is fully self-contained. Zero external resources, zero network requests.
