/*
 * ============================================
 *  MODAL / LIGHTBOX COMPONENT
 * ============================================
 *
 * A reusable modal system used across the site:
 * - Service detail modals (Services page)
 * - Project detail lightboxes (Portfolio page)
 * - Product quick view (Shop page)
 *
 * How modals work:
 * 1. A dark overlay covers the entire screen
 * 2. A centered content box appears with a scale animation
 * 3. The background page cannot be scrolled
 * 4. Close via: X button, clicking overlay, pressing Escape
 * 5. Focus is trapped inside the modal (accessibility)
 *
 * Accessibility:
 * - role="dialog" and aria-modal="true"
 * - aria-labelledby points to the modal title
 * - Focus trap keeps keyboard navigation inside the modal
 * - Escape key closes the modal
 * - Focus returns to the triggering element on close
