A critical resource (like a font, image, or script) needed for the initial render of your page is being discovered and loaded late in the process. This delays when users see and interact with your content, impacting Core Web Vitals.
A critical background image defined in CSS is loaded only after the CSS file is parsed.
Add a `<link rel="preload">` tag in the `<head>` for critical resources to ensure they start downloading immediately.
<link rel="preload" as="image" href="background-hero.jpg">Preloading tells the browser to fetch critical resources earlier, reducing the time to First Contentful Paint (FCP) and Largest Contentful Paint (LCP).
