/* globalapps.top, qsvo.globalapps.top, diwass.globalapps.top and aschg.globalapps.top (backend#120, #122, #124), served to all from
   /gemeinsam/. Layout: a course page in the online-course idiom — a dark course header, a sticky course card on the
   right, a collapsible curriculum below; a lesson player with narrated slides, tabs and the curriculum alongside; plain
   pages for the survey, the Impressum and the privacy notice; and the page on globalapps.top that lists the courses.
   Each course has its own colours: green for the QS-VO course (the default), blue for DIWASS (data-kurs="diwass"),
   amber for the ASchG course (data-kurs="aschg").
   The fonts are the visitor's own system fonts on purpose: nothing on these sites loads from another server. */
