/**
 * @file
 * Basic Card Component
 * 
 * A modern, modular card component for showcasing workshops, projects, or portfolio items.
 * Features golden ratio image, animated reveal, and hover zoom effects.
 * 
 * USAGE:
 * ------
 * <div class="basic-card">
 *   <div class="basic-card-image">
 *     <img src="your-image.jpg" alt="Description">
 *   </div>
 *   <div class="basic-card-content">
 *     <h2 class="basic-card-title">Title</h2>
 *     <h4 class="basic-card-subtitle">Subtitle</h4>
 *     <p class="basic-card-description">Description text...</p>
 *   </div>
 * </div>
 * 
 * DESIGN PRINCIPLES:
 * ------------------
 * - Golden ratio image aspect (1.618:1)
 * - 8px rounded corners
 * - White background with shadow
 * - Visible modularity through staggered animations
 * - Hover zoom on image with hidden cursor
 * 
 * ANIMATION OPTIONS:
 * ------------------
 * Add "basic-card-animate" class to enable scroll-based reveal animation.
 * Each element (image, title, subtitle, description) animates sequentially.
