Я знаю, что файл класса чувствителен к регистру при загрузке и создании.
Но я автоматически загружаю библиотеку карабина и называю css как
$this->carabiner->css($css_assets);
Все они работают нормально на сервере разработки. Но он не работает на производственном сервере (Linux). Как и предполагалось, сервер Linux, проверяющий класс, чувствителен к регистру.

Как решить класс CSSMin для автозагрузки с файлом класса Carabiner.
