I'm setting up an HTML file with p5.js to create a flow field visualization.

Done. `index.html` is a self-contained single-page flow-field particle animation. Key features: - **4000 particles** advected by a Perlin-noise vector field (angle = `noise(x,y,z)` mapped to direction). - **Fading trails** via a translucent black rect drawn each frame instead of clearing. - **Colors shift over time** — `hueBase` drifts continuously, combined with position and speed for HSB coloring. - **Time-evolving field** — the noise `zoff` dimension animates the flow slowly. - **Interactivity** — mouse position pushes nearby particles away; clicking reseeds all particles. - Loads the local `p5.min.js` with a plain `<script src="p5.min.js">`, no external resources, and handles window resize. Open it in a browser to run.
