/**
 * C8Y Empty State - Empty state component for lists and containers
 *
 * Note: Uses @size-* tokens for spacing; @size-base for calculations, and @component-padding.
 *
 * Intentionally hardcoded values:
 * - Component-specific dimensions (600px, 280px, 45px): Max widths and flex basis
 * - Typography sizes (30px, 90px): Large icon font sizes
 * - Opacity values (0.6): Visual effects
 * - Percentages (100%): Layout
 * - Rem values (8rem, 4rem): Responsive padding using rem units
