/* /courses/classes — the new design arm.
 *
 * Self-contained: classes.php sets $pageCssOverride, so this replaces the
 * page's stylesheet list and nothing here has to out-specify offline-classes.css.
 * head.php prepends chrome-flat.css for the header and footer.
 *
 * Same language as the other new arms — radius 0, 2px ink borders, no shadow,
 * no gradient. A schedule of real classes reads better as a printed timetable
 * than as a wall of floating cards.
