/**
 * Validates the `maxVideos` prop shared by the feed components.
 *
 * The native SDK treats the cap as "total number of videos ever loaded", so only a
 * positive integer is meaningful; anything else is ignored (no cap) and the caller
 * is expected to warn.
 *
 * @returns the value when it is a positive integer, otherwise `undefined`.
