/**
 * Pagination
 * 
 * Pagination components allow users to navigate between pages of content,
 * indicating the current page, total number of pages, and providing navigation
 * controls to move between pages.

 * @layer: components
 * 
 * Accessibility:
 * - Use proper semantic markup (nav, ul, li)
 * - Include proper ARIA attributes (aria-current="page")
 * - Ensure keyboard navigability
 * - Include descriptive text for screen readers
