/* Ancient Rome stage (templates/projects/history_tutor/ancient_rome.html).
   Site edu-theme tokens only. Layout: one full-screen stage: the map fills it, a year slider runs
   along the bottom, a "Now discussing" card sits bottom-left and a drawer (facts, people, events,
   layers) slides in from the right. Gaius floats over the map's bottom-left corner as a round
   avatar; clicking it opens the chat card, and the minus button tucks it away again. */
