// VITEST SETUP
// =============================================================================
// This file runs before every test suite and sets up the testing environment.
// It imports jest-dom matchers which add custom assertions like:
//   - toBeInTheDocument()
//   - toHaveTextContent()
//   - toBeVisible()
//   - toBeDisabled()
//   and many more.
//
// See: https://github.com/testing-library/jest-dom
