Need create index.html in /workspace with p5.min.js local. Need full-screen flow field particle animation with thousands particles advected by Perlin noise, fading trails, colors shifting, all self-contained, inline CSS/JS. Need a html file that loads p5.min.js exact filename. Need implement in global mode likely. Need maybe use createCanvas(windowWidth, windowHeight) and noSmooth? Need performance. Need background fade for trails each frame with alpha. Need vector field maybe computed on fly via noise(x*scale, y*scale, zoff). Need array of particles. Thousands (maybe 3000). Need color shift over time using HSB or colorPalette noise. Include respawn edges or random respawn. UI maybe none. Ensure full screen no scroll. Use p5.colorMode maybe HSB. Let's check current directory for p5.min.js.

Need create index.html single self-contained. Use p5.min.js local. Full-screen flow field with thousands particles. Use global p5. Need ensure performance. Plan: setup full canvas windowWidth windowHeight, create particles array 4000. Flow field grid, compute vectors via noise(x*scale, y*scale, zoff) every maybe every 10 frames or partial. Use pixel manipulation for fading trails? p5 drawing translucent background per frame is OK for thousands? Could use background(0,10) each frame, then particles drawn with additive colors. Fading trails via background low alpha. Need color shifting over time: use HSB or color with hue mapped to noise/time/position. Use global mode. No external resources. Also maybe interaction: click reset, resize. Need full screen no scroll. Let's write.

Built `/workspace/index.html`: a full-screen flow-field animation using the local `p5.min.js`. Features ~4,200 particles, Perlin-noise-driven vectors, fading trails, and HSB colors shifting over time. Click anywhere to restart the field.

EVALUATION
Flow-field particles render but quickly devolve into full-screen horizontal scanline noise, looking broken rather than fluid.

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.
