/**
 * Loading skeleton component for better perceived performance
 *
 * ## Business Perspective
 *
 * Improves perceived performance by showing content placeholders while
 * data loads, making the application feel more responsive and reducing
 * user anxiety during loading operations. 📊
 *
 * ## Technical Perspective
 *
 * Provides animated placeholder content that mimics the structure of
 * the actual content being loaded. Uses CSS animations for smooth
 * skeleton shimmer effect. Supports multiple variants for different
 * widget layouts.
 *
 * @example
 * ```tsx
 * // Default 3-line skeleton
 * <LoadingSkeleton />
 *
 * // Custom number of lines
 * <LoadingSkeleton lines={5} />
 *
 * // Summary widget skeleton
 * <LoadingSkeleton variant="summary" />
 *
 * // Chart widget skeleton
 * <LoadingSkeleton variant="chart" />
 *
 * // Metrics widget skeleton
 * <LoadingSkeleton variant="metrics" />
 * ```
