It draws its artwork with CinemaHeroArtwork, and shows the same first
video as the poster's View details on Available courses. The mark reads Level N
or Reference, and Enrolled once the learner joins. On wide screens a
chip names the first video; it is deliberately not a link, because opening
a video enrolls the learner (capability course-enrollment). The facts line
counts modules as lessons and lessons as videos (course-vocabulary), and
the prizes render as silhouettes: nothing is claimed before joining. The
description is shown in the active locale through courseCopy; the title
is never translated.
The course page's opening frame: the course's first video's artwork, what kind of course it is, how big it is, and the enroll action.
