Done — `index.html` contains the full fireworks display. Features: - **Click to launch**: a shell arcs up from the bottom toward your click point and explodes near apex - **Gravity-affected particles**: sparks decelerate with drag, fall under gravity, and fade with per-particle flicker and motion-trail streaks - **Burst variety**: spherical, ring, and double-hue double-burst shells in random colors - **Explosion flashes**, glowing shell trails, and a twinkling starfield backdrop - **Spacebar** fires a staggered random barrage; idle auto-shows occasionally - Fully self-contained, no network or external assets

EVALUATION

4/5 working

Fireworks launch and explode into colorful particle bursts on click, drag, and space; arrows/WASD had no effect as expected.

Vision grade · anthropic/claude-sonnet-5

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.
