# Dia Gradient

> Dia Browser's signature aurora glow — a rainbow field anchored to the bottom that rises up on mount via a scaleY transform, unfurling from the floor like an aurora. Zero dependencies, no canvas, no per-frame work. Ships four self-contained renderings of the same idea: DiaGradient (a bell-curve row of tall, heavily-blurred full-rainbow columns — the original footer look), PeakedGradient (stacked smooth bezier peaks, light front to dark back, one soft mountain of colour with a pointiness control and a scroll-driven reveal option), FoldGradient (the bar field on a 3D plane folded away from the viewer via CSS perspective and rotateX, like a glowing floor receding toward a horizon), and DodgeGradient (a vertical black-to-white fade color-dodge-blended over a horizontal rainbow, masked into a dome bloom). Each honours prefers-reduced-motion and is a drop-in background layer.
