## Prompt that renders it frame-exact

Use the Vanta.js Rings effect (https://www.vantajs.com/?effect=rings, MIT, source github.com/tengbao/vanta/blob/master/src/vanta.rings.js) as a full-frame background for a loading, progress or launch-countdown beat. Load three.js r134 and vanta@0.5.24/dist/vanta.rings.min.js and mount VANTA.RINGS with mouse, touch and gyro controls off. Each ring adds its own rotation step on every requestAnimationFrame, so seed Math.random before init (ring sizes and colors are random), cancel effect.req and step it yourself 60/fps times per video frame, in order from frame 0: each step adds 1 to effect.t, calls effect.onUpdate() and then effect.renderer.render(effect.scene, effect.camera). Set backgroundColor and the base color from the brand; edit the effect's colors list if the default neon mix clashes.
