Art style: Cinematic Realistic.
A massive, rusted steel vault door sliding across a heavily reinforced concrete threshold. The survivor stands small in the frame, taking a hesitant step backward toward the warm, golden-lit interior of the hidden civilization. Behind the door, blurred silhouettes of pipes and glowing amber hydroponic plants are visible. Shot as a wide establishing shot framing the survivor between the golden sanctuary and the pitch-black subway tunnel. The lighting contrasts the inviting, rich golden glow of the interior with the cold, dead darkness outside. The atmosphere is urgent and emotionally conflicted. The color palette is split between vibrant amber and oppressive black.

FINAL STYLE ENFORCEMENT (this is the authoritative rendering directive — it overrides any style wording elsewhere in the prompt):
Render this image entirely in "Cinematic Realistic" style. Match the lighting grammar, material response, colour science, level of realism / stylisation, line weight, and shading model typical of "Cinematic Realistic". Keep the subject, composition, camera angle, lighting direction, and colour palette from the description above — but EVERY surface, skin, fabric, material, and environmental element must be rendered in the "Cinematic Realistic" idiom, not in any other medium.
