/**!
 * @file ViewLesson.css
 * @desc Modern reading shell for the public-facing lesson view page
 *       (esl_viewLesson.php).
 *
 *       Layout: 2-column at desktop (article + right sidebar with sibling
 *       lessons + teacher card). Article is a single white "page" with
 *       hero header → optional hero image → passage prose → optional
 *       audio / translation / map / vocabulary / quizzes / comments.
 *
 *       All rules scoped under body.view-lesson so nothing leaks. Plays
 *       cooperatively with the legacy `highlightword`, `figure` and
 *       Bootstrap `card`/`form-control` styles still loaded for the
 *       embedded passage images and the comments form.
