/**
 * The services layer is organized as follows:
 *
 * - `services/utils.ts`: Core API utilities that handle authentication,
 *   request formatting, and common CRUD operations.
 *
 * - `services/[table]/query.ts`: Table-specific API methods that use the core utilities
 *   to interact with specific API endpoints. Each table has its own query file with
 *   specialized methods for that data type (e.g., courses, users, etc.).
 *
 * - `services/[table]/mock.ts`: Mock implementations of the same methods found in query.ts.
 *   These files serve as drop-in replacements for development or testing purposes.
 *
 * ## Mock Implementation
 *
 * The mock.ts files implement the EXACT SAME interface as their query.ts counterparts.
 * This means:
 *
 * - All method signatures are identical (same names, parameters, and return types)
 * - All exported types and interfaces are identical
 * - The mock implementations return realistic data structures that match what the API would return
 *
 * This allows for easy switching between real API calls and mock data by simply changing imports.
