/* Lesson page (forked from study_page/css/study.css).
   Dutch text is set in a serif (ink), English in a sans (muted), word meanings in small sans:
   the three kinds of text never look alike. The current line gets a highlighter mark.
   Colours follow the channel: teal accent, warm paper; "de" words blue, "het" words orange.
   Shared tokens (--paper, --ink, --accent ...) are defined in site.css, which loads first. */
