Each card is one episode in an Infinigen underwater scene (coral reef, kelp forest, open seabed): scuba divers modelled on real dive footage (guided groups and buddy pairs; swimming, hovering, photographers, hand signals, safety stops; neoprene, BCD, tank, hoses, fins; mask-top action cameras), a fleet of ROVs, or a school of real2sim fish with fin tags; seawater with depth- and colour-dependent attenuation. Reef camera looking up, photographer at depth, boat hull camera, then the egos' own cameras. Track A query: given one ego view and one exo view, pick the one who wears it.
