/**
 * SPONGE CAROUSEL STYLES
 * Boutique, high-velocity creative developer carousel
 * 
 * Features:
 * - Wide landscape aspect ratio (long lengthwise, not heightwise)
 * - Zero gaps and zero borders: directly connected edge-to-edge image band
 * - Symmetric vertical press squish (human hand depression in the center)
 * - Continuous, seamless C1-smooth curved contour across the entire band
 * - Inward-snuggling content hierarchy that adapts dynamically to the pinched waist
 * - Elastic spring recovery when scrolling settles
