Sticky Header

Create a Sticky Header pattern for an AI-generated interface. It should help with pin navigation to the top as the user scrolls past it. Use a restrained black, white, and gray visual style, strong hierarchy, and product-grade spacing. The interaction should feel persistent, practical, and easy to scan.

Do not make the sticky header 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.
