/**
 * Services Layer
 *
 * This module provides a centralized business logic layer for the application.
 * Services encapsulate complex operations and database interactions, keeping
 * API routes thin and focused on HTTP concerns.
 *
 * ## Service Pattern
 *
 * Each service:
 * - Uses static methods for stateless operations
 * - Handles database operations through Prisma
 * - Provides validation and business rule enforcement
 * - Logs significant events
 * - Throws descriptive errors for failure cases
 *
 * ## Usage
 *
 * ```typescript
 * import { CartService, OrderService, ProductService } from '@/services';
 *
 * // In API route
 * const cart = await CartService.getCart(userId);
 * const order = await OrderService.create(orderData);
 * const product = await ProductService.getBySlug(slug);
 * ```
