First-person POV dive footage.

First-person POV dive footage. A scuba diver descends into a pitch-black ocean. The only light is the diver's torch cutting a narrow beam into the dark. At depth, the torch clicks off. Total darkness for two seconds. Then — faint blue pulses. Bioluminescent creatures begin appearing in the void: a jellyfish drifts past, trailing light. A school of fish materialises as a glowing spiral. The diver reaches out slowly; the fish scatter like sparks. Camera pans across the dark to reveal a vast structure of glowing coral below. Slow exhale audible on the soundtrack. No music.
