/**
 * ICA Past Faculty Slider Styles
 * 
 * Optimized for performance with CSS Grid, scroll-snap,
 * and responsive design. Includes accessibility features.
 * Features faculty member cards with name, role, and credits.
 * 
 * INTEGRATES WITH SITE GRID RAILS SYSTEM:
 * - Uses grid-column: full-start / full-end for full-width edge-to-edge display
 * - Background spans entire viewport width
 * - Internal content has proper spacing via padding-inline
 * - Leverages CSS custom properties for consistent spacing
 * 
 * @package Illinois_Conservatory
 * @since 1.0.0
