   BUSINESS LAB — стилі сайту
   Світла тема за замовчуванням; темна вмикається атрибутом data-bl-theme="dark"
   на <html> (кнопка в шапці). Усі кольори — змінні CSS у :root.

   Зміст:
     1. Змінні: кольори теми й кафедр
     2. Фон, шапка, біжучий рядок кафедр
     3. Екрани, панелі, кнопки
     4. Старт: реєстрація, «Продовжити гру», інфографіка кафедр
     5. Поле карток і вікно запитання
     6. Результат і рейтинг ТОП-100
     7. Вікно «Поділитися результатом»
     8. Адаптивність (планшети, телефони, великі екрани)
     9. Заставка (перша сторінка)
