/**
 * Keeps clipped content understandable by signalling where people can keep
 * scrolling.
 * The component renders a native viewport and can show token-backed fades at
 * its logical inline or block edges. Set `axis` to the scroll direction, use
 * `fade` to choose the visible edge cues, and match `fadeColor` to the
 * surrounding Unity surface.
 * @param props - Viewport content, scroll-axis, and edge-fade options.
 * @see {@link ScrollAreaProps} for all available props.
 * @example
 * ```tsx
 * import { ScrollArea } from '@payfit/unity-components'
 *
 * export function AttachmentPreview() {
 *   return (
 *     <ScrollArea
 *       axis="inline"
 *       fade="both"
 *       className="uy:h-500 uy:w-[320px] uy:bg-surface-neutral"
 *     >
 *       <div className="uy:flex uy:w-max uy:gap-100 uy:p-50">
 *         <span>Attachment 1</span>
 *         <span>Attachment 2</span>
 *       </div>
 *     </ScrollArea>
 *   )
 * }
 * ```
 * @remarks
 * - The component does not add a role or focusability, so children own their
 *   semantics and keyboard behavior.
 * - Fades are decorative and never receive pointer events.
 * - The forwarded ref and `onScroll` target the native viewport rather than
 *   the positioned root.
