⚡ SCENARIO: 07:43:22
"You're trapped in a smoke-filled building during a fire. You flip on your MistLink lantern and suddenly see your location appear on a shared map, along with messages from other survivors: 'Stairwell B clear' — the lantern is communicating through the smoke using light that your eyes can barely see, creating an invisible lifeline."
