Здесь недоработанный, но уже подготовленный прокт. Нужно дописать бэк и фронт(все на реaкте) и дописать парсер с шаблонами. Для вайбкодинга можно просто написать допиши проект. Все работает грамотно через докер, а не через сплошное хамство в сервер. После доработки: подгружаем docker-compose, инициализируем, докачиваем остальное с гита. Важно, что пока qwen не развернут - иишку подключать через апи.
