A vibrant poison dart frog lunges and clamps its jaw onto a king cobra's head. Cobra violently thrashes, hood flaring, body coiling around the frog in desperation. Frog holds an iron grip, golden eyes unwavering, throat beginning to pulse as it starts swallowing the cobra head-first. Snake tail whips wet leaf litter frantically. Camera starts at extreme ground-level macro, slowly push-zooming into the frog's eye, then pulling wide to reveal the full jungle around them — indifferent, vast, alive. Audio: Opens with pure jungle ambience — rain, cicadas, birds. At 3 seconds a deep cello drone enters. At 7 seconds full orchestra tension swell hits. At 12 seconds drops to eerie solo piano. Narrator voice — deep British documentary tone: [0:02] "Deep in the Amazon… nature is rewriting its own rulebook." [0:06] "The cobra flares. The frog… doesn't care."
