+4. During world creation, the coauthor also creates three editable, universe-specific AI companions. A new campaign starts immediately with those companions and an owner-controlled hero. Additional players create a human character manually or ask the coauthor for an editable draft; owners can add more AI companions the same way.
 5. The owner creates an expiring private invite link. Signed-in email users join through `/join/:token`.
 6. Players save actions and mark them ready. The final ready action queues the round automatically; the owner can also continue without waiting.
 7. The worker resolves server-owned rolls and state, publishes narration, and opens the next round. Visible campaign tabs synchronize every two seconds and immediately when the tab regains focus.
