/* ============================================================================
   Тема нового дизайну — розділ «Курси» (views/beta-theme/teacher-course).
   Префікс класів: tb-courses-. Токени й базові компоненти — у beta.css.
   Класичні класи (.upgrade-teacher-*, .teacher-study-*, .section-list-item-link-*) лишаються в розмітці
   заради JS (app_course_test.js, upgradeApp) і перестилізовані тут у межах .tb-courses.
