Art style: Cinematic historical documentary, photorealistic, dramatic oceanography and archival map details.
A visual timeline across three eras: the sea above Ferdinandea in 1863, a modern sonar-like view of a submerged reef six meters below the surface in 2000, and an Italian diver placing a small flag underwater in 2002. Cinematic yet documentary-grounded.
