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.

Created `index.html` — a full-screen p5.js flow-field animation using the local `p5.min.js` (no external resources): - **2,800 particles** (fixed, reused pool — population bounded, no growing trail history; each particle stores only its previous point) - **Perlin-noise vector field** `noise(x·0.0016, y·0.0016, zoff)` with `zoff` continuously increasing, so nearby particles move coherently and the pattern evolves indefinitely without looping - **Fading trails** via a translucent veil each frame, plus HSB colors that cycle over time (global hue shift + per-particle/field variation) - **Recycling** at canvas boundaries and at end of each particle's lifespan (respawned in place, no cross-screen streaks) - **Controls:** Pause/Resume button, Restart button (plus Space / R keyboard shortcuts), speed & trail-fade sliders, live particle/FPS/status/field-time readouts; canvas resizes to the viewport **Verified in the browser at 1200×800:** - Motion sampling over several seconds showed locally coherent swirling strands, lengthening/fading trails, shifting colors, and field time advancing (FPS ~31–56) - Pause froze the frame and switched the button to "Resume" / status to "Paused"; Resume restored motion - Restart instantly cleared all trails, showed a fresh scattered particle arrangement with a new noise seed/field time, and trails regrew into a new pattern Unverified: very long-run memory behavior (guaranteed structurally by the fixed array/prev-point-only design, not stress-tested) and behavior on non-1200×800 viewports beyond the implemented resize handler.
