/**
 * Content Loader - Centralized content management
 * 
 * This module provides type-safe access to all JSON content files.
 * Content can be easily modified by editing the JSON files without code changes.
 * 
 * Usage:
 * import { content, getPageContent } from '@/content'
 * 
 * // Access specific page content
 * const aboutContent = content.pages.about
 * 
 * // Or use the helper function
 * const servicesContent = getPageContent('services')
