Measures the time until the first content is painted on the screen.
FCP is a performance metric that measures the time from when a page starts loading to when any part of the page's content (e.g., text, an image) is rendered on the screen.
It's a key user-centric metric because it marks the first point at which a user sees that the page is actually loading. A fast FCP provides positive feedback and keeps users engaged.
A slow FCP can make users feel like the page is broken or slow, leading them to abandon the site.
