How to use this charcoal to slate to slate gradient

This linear gradient can be used as a hero background, dashboard card treatment, app shell backdrop, social visual, or landing page accent. The color sequence is parsed directly from the URL, which means the page can be shared, indexed, and revisited.

The export system creates a standard CSS fallback, a perceptual multi-stop fallback, and a modern OKLCH declaration where appropriate. That makes the output useful for production interfaces, not just screenshots or static inspiration boards.
