/* Grammar Practice.

   The pages are built from components the site already has, so this file only
   adds what those do not:
     hub         css/practice-exercises.css  px-hero, px-how, px-secs, px-card
     skill page  css/lesson.css               lesson-hero, lesson-shell, lesson-block,
                                              lesson-table, lesson-paywall
   It loads last on both. Anything inside .lesson-main has to beat that file's
   (0,1,1) element rules, which is why some selectors below carry two classes. */
