Using the pre-provided p5.min.js (global p5, instance or global mode), create a full-screen flow-field particle animation: thousands of particles advected by Perlin-noise vectors, leaving fading trails, with colors shifting over time.

The user wants me to create a single-page web app with a flow-field particle animation using p5.js. The requirements are: 1. Full-screen canvas 2. Thousands of particles 3. Particles advected by Perlin-noise vectors (flow field) 4. Fading trails 5. Colors shifting over time 6. All in one self-contained index.html file 7. Use the pre-provided p5.min.js with a plain script tag Let me create this animation. I'll use p5.js in global mode for simplicity.

I've created the index.html file with a complete flow-field particle animation. Let me verify it exists.

Created `index.html` with a full-screen flow-field particle animation featuring: - **5000 particles** advected by a 3D Perlin noise vector field (x, y, time) - **Fading trails** using semi-transparent black rectangles each frame - **HSB color cycling** - hues shift over time with per-particle variation - **Velocity-based brightness** - faster particles glow brighter - **Wrap-around edges** - particles reappear on opposite side - **Responsive** - adapts to window resize
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.

EVALUATION
Only a handful of colored trails visible instead of thousands of particles; sparse flow-field effect, mostly black canvas.
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.
