Prompt for this run

Build a full-screen flow-field particle animation using the provided p5.js library in global or instance mode. Use HTML, CSS, and JavaScript as needed. Write it to `index.html` in the current working directory using your file tools. Inline your own CSS and JavaScript. Do not use external assets, CDNs, or network requests. Use the provided `p5.min.js` (global `p5`) through a plain local script tag; the runner will inline it into the final artifact. Required behavior: - Animate at least 2,000 particles, with motion guided by a smoothly varying Perlin-noise vector field. Nearby particles should follow locally coherent directions. - Leave fading trails and vary particle colors over time. Evolve the field gradually so the pattern changes instead of repeating a short recorded sequence. - Recycle particles at the canvas boundaries and keep the population bounded. Avoid allocating an ever-growing trail history. - Provide Pause/Resume and Restart. Restart clears trails and initializes a new particle arrangement. - Fit the viewport and keep controls responsive at 1200 by 800. Choose the palette, field scale, and particle speed freely. Verify: Sample the animation at several moments to inspect coherent nearby particle motion, fading trails, and changing colors. Pause and resume, then use Restart and check that the trails clear and a new arrangement appears.

The animation is running with coherent flow-field streaks and varied colors. Let me sample at a later moment to verify trails accumulate and colors shift.

Trails are accumulating nicely with coherent swirling flow and shifting colors. Now let me test Pause/Resume and Restart.

Paused (button now shows "Resume"). Let me verify the frame is frozen by taking another screenshot, then resume and test Restart.

The frames are identical while paused — animation is frozen correctly. Now resume and test Restart.
