    "text": "Welcome to Gallery Twelve, home of the Harrow Collection. Please pause in front of the porcelain crane with cobalt feathers and a gold-tipped beak. At first glance, it appears delicate, almost weightless, yet the base is reinforced with hidden iron pins, a technique used to protect objects that were expected to travel long distances. If you look closely at the label, you may notice a discrepancy. The accession number ends in 314. The crane before you ends in 341. That is not a printing error. Security has asked that visitors remain where they are and avoid the east corridor. A replacement has been placed on display within the last seven minutes. The original artifact is missing. If you are wearing a gray wool hat, carrying a folded map, and standing nearest the skylight, this message is for you: the case you opened triggered a silent pressure alarm. Please set the object down carefully. Museum staff are approaching, and no one needs to get hurt. For all other guests, thank you for your patience. The tour will resume shortly.",

Secure loose equipment on piers, move away from exposed breakwaters, and keep access roads clear for response crews. If you are already on the water and cannot return safely, contact harbor control on channel sixteen and report your location, vessel color, and number of passengers. Repeat: small craft return to dock immediately. Further updates will follow in ten minutes.",
