Soft, blurred colour washes for hero backgrounds — a warm core, a cool halo, a little grain.
Shape it, tune it, then take it away as paste-ready CSS that needs no JavaScript, a PNG, or a
config you can share. Same seed, same glow.

Motion
Your system asks for reduced motion, so the preview (and the exported CSS) holds a still frame.
Seed
Randomize rolls a new seed; a seed always rebuilds the same glow.
CSS · paste into any site
Layered radial gradients + filter: blur() + grain. No JavaScript.
PNG snapshot
