/**
 * Base Jest Configuration for next-core Applications
 *
 * All demo apps should extend this configuration for consistency
 *
 * @example
 * In your app's jest.config.js:
 * ```js
 * const baseConfig = require('@kodeme-io/next-core-testing/jest-config')
 *
 * module.exports = {
 *   ...baseConfig,
 *   // Your app-specific overrides here
 * }
 * ```
