/**
 * @lilith/eslint-config-react-lib
 *
 * ESLint configuration for React LIBRARIES.
 * Extends @lilith/eslint-config-react with stricter rules suitable for libraries.
 *
 * Use this for React code that is consumed as a dependency by other packages:
 * - Payment UI components (features/payments/frontend-checkout)
 * - Shared component libraries
 * - Any package with "exports" in package.json
 *
 * Key differences from react-app:
 * - NO @/ import alias enforcement (libraries must use relative imports)
 * - Stricter console rules (libraries shouldn't pollute consumer logs)
 * - Stricter type export requirements (libraries should have explicit types)
