  Student display integration notes:
  - app.js currently writes .display, .activity, .title, .subtitle, .timer,
    .next, .article-board, .article-overline, .article-content,
    .article-headline, .article-summary, .article-topic, and .article-footer
    into the child window as inline CSS.
  - When the parent can share a stylesheet with rostraStudentDisplay, move the
    presentation tokens below into that template instead of duplicating them.
  - Keep the display private-safe: no filler counts, roster statuses, grades, or
