    🧪 What is PHPUnit?
    PHPUnit is the standard testing framework for PHP.
    It lets you write automated tests that verify your code works correctly.
    
    Run tests with: composer test
    Or directly:    vendor/bin/phpunit
    
    With coverage:  vendor/bin/phpunit -coverage-html coverage/
