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

I'll create a full-screen fireworks display with gravity-affected particles that fade out. Here's the complete implementation:

I've created a full-screen fireworks display with the following features: **Core Mechanics:** - **Click to launch**: Click anywhere on screen to fire a shell toward that location - **Gravity-affected particles**: Each explosion creates particles with realistic downward acceleration - **Fading particle bursts**: Particles gradually fade out based on their remaining life - **Trail effects**: Shells leave glowing trails as they ascend **Firework Types:** - **Ring explosions**: Circular pattern of particles - **Dense bursts**: Concentrated spherical bursts - **Standard explosions**: Classic firework spread **Visual Effects:** - 8 different color palettes (red, blue, green, yellow, purple, orange, cyan, pink) - Glowing particles with soft bloom effects - Fading trail marks behind ascending shells - Smooth particle decay with alpha blending - Auto-fire mode for continuous ambient display **Technical Details:** - Single self-contained HTML file with inline CSS and JavaScript - Canvas-based rendering optimized for performance - Responsive design that adapts to window resizing - Touch support for mobile devices - Particle physics with velocity decay and gravity - Particles fade out naturally as they lose energy Simply open `index.html` in any modern browser and click anywhere to launch fireworks!

EVALUATION

4/5 working

Fireworks launch and explode with colorful particle bursts on click, drag, and scroll; auto-launches when idle; keys have no effect as expected.

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.
