/**
 * A footer container that measures its height for scroll calculations.
 *
 * This component measures its height and provides it to the viewport context
 * so the auto-scroll system can account for any sticky footer overlapping the
 * message list.
 *
 * Multiple ViewportFooter components can be used - their heights are summed.
 *
 * Typically used with `className="sticky bottom-0"` to keep the footer
 * visible at the bottom of the viewport while scrolling.
 *
 * @example
 * ```tsx
 * <ThreadPrimitive.Viewport>
 *   <ThreadPrimitive.Messages>
 *     {() => <MyMessage />}
 *   </ThreadPrimitive.Messages>
 *   <ThreadPrimitive.ViewportFooter className="sticky bottom-0">
 *     <Composer />
 *   </ThreadPrimitive.ViewportFooter>
 * </ThreadPrimitive.Viewport>
 * ```
