A living field of copper on stone
A hand-written GLSL fragment shader — layered simplex noise, domain-warped so the field flows instead of tiles. It reads as mostly warm stone with soft copper veins drifting through, slow enough to feel expensive. Not a stock gradient; a surface computed per-pixel, every frame.
static gradient · reduced-motion / no-WebGL fallback
The copper is thresholded to stay a highlight, never the whole canvas — same rule as everywhere else in the palette: stone is the world, copper is the accent.
