CristianOlivera1/Aura ? reverse-engineered prompt

Build me a polished web app for exploring and creating soft ambient backgrounds that feel like light. I want a gallery of 200 plus layered gradients that I can hover to preview instantly, then open in a fullscreen viewer with next and previous controls and keyboard shortcuts. The whole page should softly reflect the active gradient so it feels immersive in both light and dark mode.

Also add a simple editor where I can tweak the gradient in the browser, add or remove layers, reorder them, change blend modes, blur, opacity, and base color, and turn a grain overlay on or off for a more organic look. It should support undo and redo while I experiment.

Let me export the finished result as clean CSS, Tailwind, CSS variables, or CSS in JS, copy everything at once, and download the gradient as PNG or SVG. I’d also like one click to copy a prompt that helps recreate the same gradient in ChatGPT, Claude, or Copilot.
