Create a fireworks display on a full-screen canvas where clicks launch shells that explode into gravity-affected, fading particle bursts.

The user wants a fireworks display web app with:
1. Full-screen canvas
2. Click to launch shells
3. Shells explode into particles
4. Particles are gravity-affected
5. Particles fade out
6. Self-contained in index.html

Let me create a visually impressive fireworks display with:
- Dark background
- Shell launching animation (rising then exploding)
- Particle bursts with gravity and fade
- Multiple colors
- Smooth animations
- Maybe some ambient particles or trails

Let me design this carefully.

The file has been written successfully. Let me verify it looks good by reading it back and checking the structure.

The fireworks display is ready at `/tmp/ws/index.html`. Here's what it does: - **Full-screen canvas** with a dark background and subtle ambient twinkling stars - **Click/tap anywhere** to launch 2–4 shells from that position - **Shells rise** with a fading trail, affected by gentle gravity, then explode at their apex - **Explosions** produce 60–120 colored particles plus 20 white spark particles per burst - **Particles** have gravity pulling them down, air friction slowing them, and smooth fade-out - **Auto-launches** occasional shells for continuous ambiance even without interaction - **8 color palettes** rotated randomly across shells - **Touch support** for mobile devices Open the file in a browser and start clicking to create your display!

EVALUATION

4/5 working

Fireworks auto-launch and explode with gravity-faded particles; clicks/other inputs also trigger new colorful bursts.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
