/* Deep Dive 5 - "read it to me" buttons.
 * A block that has a recording gets a small Listen button. Asked for by Lilah, a student
 * reviewer, 2026-10-10. Nothing plays until the reader presses it: no autoplay, ever,
 * because a page that starts talking by itself is worse than one that stays quiet.
 * Scoped to .dd5-audio* so it cannot touch anything that does not opt in.
