/* Presentation timer (presentation-timer.php). Loaded after pdf-tools.css so the hero, option
   cards, fields and FAQ grid are shared. Adds the settings/queue column, the stage with the giant
   clock and its tone states (ok → warn → final → over), the time log and a full-screen projector
   mode where the digits scale to the viewport. */
