 * Course overview and questions modules.

 * questions block in course-qna.blade.php.
 *
 * Design intent for the overview: an open, editorial composition on the
 * light page background rather than one boxed card. A centred statement,
 * the three laws as a numbered rail, one split panel for employers and
 * employees, and a dark proof board that closes the argument. Type is
 * large and high contrast. Motion is hover feedback only and is disabled
 * under prefers-reduced-motion.
