Preserve the exact single vertical D-03 Storm from the uploaded anchor on a mathematically pure black #000000 matte with a completely fixed camera. Use the uploaded portal image only as a reference for turquoise color, luminous water energy and abyssal depth; regenerate the complete moving portal inside this shot and do not paste the reference texture. Create one four-and-a-half-second atomic finale containing the dolphin and exactly one coherent underwater portal as one inseparable continuous scene. Hold the exact anchor for 0.35 seconds. Then one compact circular abyssal water gateway forms below and slightly in front of Storm, built from a single continuous turquoise current with a dark deep center and one physically consistent front water lip. Storm notices it, lowers the head, steers with both pectoral fins, bends the complete spine and actively swims into the same gateway with two strong articulated tail strokes. The head, torso, fins and complete tail cross the opening in anatomical order. The gateway's own front water lip naturally occludes the same body during entry; this occlusion is generated inside this video, not added later. After the tail disappears, the single gateway contracts smoothly and closes. End with at least 0.35 seconds of completely empty pure black. Keep the complete composition inside the central eighty percent safe area so the same source can be mirrored for the opposite reservoir. Preserve one dolphin, constant anatomy and believable underwater mass.
