File written, will verify.

Created `/tmp/ws/index.html` — a full-screen fireworks display featuring: - **Click to launch**: Click anywhere to fire a shell from the bottom toward your cursor - **Gravity-affected particles**: Explosions with realistic arc and fade - **Three explosion types**: sphere burst, ring burst, and double-color burst - **Color palettes**: 8 vibrant palettes with glow effects - **Shell trails**: Glowing sparks follow each rising shell - **Ambiance**: Twinkling star background and occasional auto-launches - **Touch support**: Works on mobile too - **Smooth fade**: Canvas trails for that classic firework glow Open `index.html` in a browser and start clicking!
