The user wants a single-page web app using p5.min.js (already present in /tmp/ws) that creates a full-screen flow-field particle animation. Let me build this with: 1. Thousands of particles advected by Perlin noise vectors 2. Fading trails (draw semi-transparent background each frame) 3. Colors shifting over time (hue rotation over time) 4. All in one index.html file with CSS in <style> and JS in <script> 5. Load p5.min.js via <script src="p5.min.js"></script> Let me first verify p5.min.js exists.

The user asked for a full-screen flow-field particle animation using p5.js. I've created a complete, self-contained `index.html` file that: 1. Uses the local `p5.min.js` file (loaded via `<script src="p5.min.js"></script>`) 2. Creates a full-screen canvas with `createCanvas(windowWidth, windowHeight)` 3. Spawns 5000 particles that are advected by 3D Perlin noise vectors 4. Particles leave fading trails via semi-transparent background overlay (`fill(0, 0, 0, TRAIL_FADE)`) 5. Colors shift over time using HSB color mode with a rotating hue base 6. Uses velocity smoothing for natural-looking flow 7. Handles window resizing 8. No external resources or CDNs - everything is self-contained The file is complete and should be working. Let me confirm the file exists.
Created `index.html` in `/tmp/ws/` — a full-screen flow-field particle animation with: - **5,000 particles** advected by 3D Perlin noise vectors - **Fading trails** via semi-transparent background overlay each frame - **Time-shifting colors** using HSB mode with a slowly rotating hue base - **Velocity smoothing** for natural, organic flow - **Edge wrapping** so particles reappear on the opposite side - **Responsive** — resizes with the browser window - Uses the local `p5.min.js` via `<script src="p5.min.js"></script>`, no external resources

EVALUATION
Flow-field trails render and shift color, but density collapses from thousands of streams to a few lines over time.

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.
