/**
 * A React functional component that wraps its children in a styled container with
 * a fade-in effect upon mounting. This component is primarily used to manage the
 * visibility and transition effects of its children.
 *
 * The fade-in effect is controlled using internal state hooks that determine the
 * `opacity` and visibility of the component after mounting. Styles are dynamically
 *
 * applied to facilitate the transition.
 *
 * @type {React.FC<Props>}
 * @param {Props} props - The props object that includes the children elements to be wrapped.
 * @property {React.ReactNode} props.children - The content to be rendered inside the component.
 * @remarks
 * - Internal state `mounted` manages the initial setup for visibility and positioning
 *   before the component is fully mounted.
 * - Internal state `fadeIn` controls the gradual appearance of the component after the
 *   mounting is initialized.
 * - Uses `useEffect` to trigger the fade-in transition with a brief delay.
 * - Styled using inline `Box` styles to handle positioning, visibility, and transition effects.
