/**
 * Caption
 * 
 * Captions provide additional contextual information for images, tables, figures,
 * or other media content. They help users understand the content and provide 
 * necessary explanations or attributions.
 * 
 * @layer: components
 * 
 * Accessibility:
 * - Use appropriate HTML semantics (figcaption with figure)
 * - Maintain sufficient text contrast
 * - Don't rely on captions alone for conveying critical information
