/* ===== Free time with course friends ======================================
   Styles for the "Friends in this course" picker, the recommended-times list
   inside When2meet, and the course-detail launcher in Registration. Kept in
   its own sheet (injected on demand by when2meet.js / registration) so the
   shared styles.css stays untouched. Uses the app theme variables, so light
   and dark both work. */
