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

**Creating index.html**

I need to create an index.html file and check the current working directory. It looks like I should write it completely to ensure it satisfies the requirements. I want to build a polished, fullscreen canvas where clicks launch particles that explode and fade with gravity. Hmm, maybe I can include some auto fireworks! The user mentioned that clicks should launch, so I could add some ambient effects too. Let's get started on writing this!

**Tackling JSON issues**

I think I accidentally malformed the JSON during the write process, which resulted in a partial write. Now, I need to overwrite it completely. I'm considering creating a polished app that’s a single file. My idea is to have a full-screen canvas with clicks that launch shells and include effects like gravity and fading bursts. Maybe I could also incorporate auto fireworks and UI hints for controls? I just need to implement this without any external dependencies. Let’s write the full version!

Created `/tmp/ws/index.html` — a self-contained full-screen fireworks display with: - Click-to-launch firework shells - Gravity-affected particle explosions - Fading, glowing particles and trails - Night-sky styling with subtle stars - Responsive canvas resizing - Reduced-motion support - No external resources or network requests

EVALUATION

4/5 working

Fireworks launch and explode into colorful particle bursts on click, drag, wheel, and keyboard input, with idle auto-launching too.

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.
