Field notes
The page frames the activity as a classroom encounter: teams reason before submitting, and correct answers contribute to one shared attack. It lists an instructor console for preparing problems and directing a projector, alongside saved rooms and PDF projection. These are described features; the extracted page does not verify that a live encounter is currently working.
