Prompt that renders it frame-exact

Use the Vanta.js Halo effect (https://www.vantajs.com/?effect=halo, MIT, source github.com/tengbao/vanta/blob/master/src/vanta.halo.js) as a full-frame background with a logo, product shot or one word inside the ring. Load three.js r134 and [email protected]/dist/vanta.halo.min.js and mount VANTA.HALO with mouse, touch and gyro controls off. Halo feeds each frame back into the next through two render targets, so it must be rendered in order: cancel effect.req and per video frame advance effect.uniforms.iTime.value by speed/fps, then call effect.onUpdate() and effect.renderer.render(effect.scene, effect.camera), starting from frame 0. Set baseColor, color2 and backgroundColor from the brand, size 0.8–1.5 for the ring, and xOffset/yOffset to place it (it drifts a little left of centre in 16:9 by default).
