Prompt that renders it frame-exact

Use the ShaderGradient "Interstella" preset (preset 03 on https://shadergradient.co/customize, MIT; exported as presets.interstella from @shadergradient/react, source github.com/ruucm/shadergradient/blob/main/packages/shadergradient/src/presets.ts) as a cinematic full-frame background for a sci-fi, travel or tech title sequence. Install @shadergradient/react with @react-three/fiber and three, then render <ShaderGradientCanvas style={{position:'absolute',inset:0}} lazyLoad={false} pixelDensity={1}> with <ShaderGradient {...presets.interstella.props} /> inside. To make it frame-exact, override animate="off" and pass uTime={seconds} (the shader multiplies it by uSpeed 0.3), set enableTransition={false} so the camera starts in place, and let R3F draw once before each frame is captured. It is lit by an environment map (lightType "env", envPreset "city"), which loads an HDR file at startup, so preload it before rendering or set envBasePath to a local copy. Recolor color1–color3 and nudge reflection for more or less gloss.
