The Flex component is a wrapper for Tailwind's flexbox utilities. It exposes props for all common flex, direction, wrap, alignment, and justification options, as well as shortcuts for common patterns.
The FlexItem component is designed to be used as a direct child of Flex. It exposes common Tailwind flex child utilities (such as flex-1, flex-auto, flex-initial, flex-none, and flex-grow) as props, allowing for a clean, prop-driven API.
