 * Banner Component Styles - Swiper.js Implementation

 * Styles for the banner carousel system using Swiper.js with dynamic color customization.

 * Note: Text colors (hero-title, hero-subtitle) and background colors are applied 
 * via inline styles in the PHP templates to support per-banner customization.
 * Background can be either an image OR a solid color, not both.
 * This file contains only base styles and positioning rules.
