/*
 * Full Screen Infinite Slider - LUNDEV original styling
 *
 * ISOLATION FOR PLUGIN CO-EXISTENCE:
 * - All selectors start with .fsi-slider
 * - Every child class uses the fsi- prefix (fsi-carousel, fsi-list, fsi-item, etc.)
 * - Keyframe animations use the "fsi" prefix (fsiShowImage, fsiShowContent, etc.)
 * - Critical properties rely on !important to prevent overrides
 * - Ensures compatibility with GreyWay Slider and other plugins
