/* Lesson body content styles — markdown rendering, supplementary links, and
   document resources shown within a lesson's content column. Split out of
   library.css (issue #411) purely for the 800-line file cap; this is the
   same precedent as video-player.css's split (see library.css's comment
   near .lesson-text). */
