Aurora Background

Create a Aurora Background pattern for an AI-generated interface. It should help with shifting aurora borealis gradients for immersive hero sections. Use a restrained black, white, and gray visual style, strong hierarchy, and product-grade spacing. The interaction should feel ethereal, practical, and easy to scan.

Do not make the aurora background flashy, noisy, over-animated, or decorative for its own sake. Avoid random glow, heavy gradients, excessive borders, oversized type, unclear hierarchy, and generic SaaS filler.
