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

**Designing a Fireworks Display** I'm now focused on the foundational elements for the fireworks. I aim to build a single-page web app with a full-screen canvas. Clicking will launch the fireworks, and I plan to make the shells explode with gravity-affected, fading particles, all while adhering to the constraint of a single file, without external resources. I've got a framework in mind, and I'm keen to start testing the animation mechanics. **Defining Core Elements** I've outlined the HTML, CSS, and JS components to bring the fireworks to life. The JS will orchestrate canvas resizing and click events to determine shell launches, and the animation loop, managing shells and particles. Key classes for Shells and Particles are defined; the Particle class covers attributes like position, velocity, color, and lifespan to simulate explosions. The Shell class will trigger particle creation upon reaching its apex.

The fireworks display is now ready in `index.html`. You can open this file in any modern web browser to view the interactive fireworks. Clicking anywhere on the screen will launch a projectile that explodes into gravity-affected, fading particles.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Click and wheel trigger a firework burst, but only one small explosion is ever visible; no shell trail or gravity fall visible.

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.
