**Initiating Particle Animation** I'm starting a full-screen flow-field particle animation, focusing on achieving a visually rich experience. I'll be leveraging `p5.min.js`, and the core requirements include thousands of particles advected by a Perlin noise field, with fading trails and shifting colors to add depth and dynamism.

All requirements satisfied. A self-contained `index.html` has been created featuring a high-performance flow-field simulation using `p5.min.js`. **Key features:** * **Performance:** Uses a vector grid calculation to manage 2500 particles efficiently. * **Visuals:** Perlin-noise based vector field with time-shifting, resulting in smooth, liquid-like motion. * **Trails:** Fading effect achieved via semi-transparent background fill. * **Colors:** Cycles through the HSB color spectrum. * **Resilience:** Automatically adjusts to window resizing. You can now open `index.html` in any browser to view the animation.

EVALUATION
Sparse colorful flow-field trails on black background, but density is far too low for a 'thousands of particles' effect.
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.
