Sateen

Flowing lit fabric: broad domain-drifted folds carry fine silky striations while a satin specular band — an orbiting light caught by the cloth's gradient — sweeps across the drape. Moonlit pewter-blue, billows under the cursor. Original OGL fragment shader, offscreen-paused and reduced-motion-safe. Idles on its own when untouched — a ghost touch billows the cloth.
