Built `index.html` — full-screen Perlin flow-field with fading trails: **Animation:** ~3500 particles (600–6000 slider) advected by 3D Perlin noise vectors (`noise(x*scale, y*scale, zOff)`), `angle = noise * TAU * swirl`. Velocity damped 0.965, speed-limited, with wrapping + random respawns. `zOff` animates continuously for evolving field; second noise octave adds turbulence. Colors in HSB shift over time (`baseHue` drifts via `frameCount * shift`) + palette spread + speed-based brightness/alpha, leaving additive trails via translucent dark rect fade (`trail` slider maps to alpha). **Controls:** Particle count / speed / trail length / noise scale / swirl / color drift, 5 palettes (Nebula/Ocean/Sunset/Mono/Acid), glow/additive toggle, flow-vector overlay, pause/clear/burst/shuffle, collapsible panel. Mouse/touch warps field (curl around cursor), drag injects turbulence, click bursts particles. Uses local `p5.min.js` via `<script src="p5.min.js">` in global instance mode, all CSS/JS inline, no network requests.

EVALUATION
Beautiful flow-field particle animation with fading trails, color shifts on input, and a working control panel.
Vision grade · anthropic/claude-sonnet-5
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.
