/* /practice, the free courses.
 *
 * Additive only. Everything this file can borrow from nbop.css it borrows:
 * .wrap, .pagehead, .eyebrow, .standfirst, .action and the :root tokens are all
 * defined there and are not redefined here. What is left is the handful of
 * shapes the courses need and the rest of the site does not: a lesson rail, a
 * lesson body, the firewall note, the next-step cards and the book block.
 *
 * Class names are namespaced under their block where nbop.css already uses the
 * bare word. .step in particular exists there for something else, so the course
 * version is only ever addressed as .nextsteps .step.
