# Nebula Space Background

> A space background for dark UI: domain-warped noise clouds tinted by one hue over a near-black base with its own hue, sparse twinkling stars, film grain and a vignette. It drifts for 0-60 s with an ease-out and then rests - only the twinkle keeps ticking at a low rate, so the GPU stays almost idle. Optional hover glow: a faint light inside the clouds that follows the pointer and flickers like distant lightning. No loop mode on purpose: an endless full-screen shader is heavy on the GPU. Retina-crisp WebGL, zero dependencies.
