/* ============================
       LESSON CONTENT (GUTENBERG)
       Additive typography for the `.lesson-content` wrapper around
       `the_content()` on single-lesson.php. Lessons are text + images
       only (Video/Audio/Download Files/Media Player removed); this file
       styles the full remaining Gutenberg formatting surface using the
       theme's existing design tokens from style.css (:root).
