Siberian Lab Zombie Horror Sequence

Create a photorealistic zombie-horror sequence inside a remote high-security biological research laboratory in Siberia, Russia during a freezing winter night. The central character is a young adult Russian female laboratory worker, with natural Slavic features, fair skin, dark-blonde to brown hair tied loosely back, minimal makeup and realistic human proportions. She wears a practical white laboratory coat over a muted thermal shirt, dark blue work trousers and simple white laboratory shoes. Her appearance, face, hairstyle, clothing and body proportions must remain perfectly consistent throughout the sequence. The facility should feel isolated and distinctly Siberian: an aging Soviet-era research complex surrounded by darkness and snow, reinforced concrete walls, frosted windows, exposed pipes, heavy steel doors, old laboratory equipment, specimen refrigerators, glass containment chambers, analog instruments and modern monitors retrofitted into the older facility. Outside the windows, show faint snow blowing through the darkness. The horror should feel cold, claustrophobic and realistic, with no excessive running. Keep the infected characters frightening through slow unnatural movements, sudden jerks, unnatural head rotations, twitching fingers, blank stares and sudden close-range attacks. Then keep the rest of the infection sequence exactly as above, including: Broken test tube → contamination → dark veins → cloudy white eyes → blank expression → dark drop → lower-bunk victim → sudden attack → veins spreading → convulsions → white eyes → inhuman scream → laboratory containment failure. For the final shot, make the Russian woman stand motionless behind the laboratory observation glass while snow and darkness are visible through the distant windows, then slowly tilt her head toward the camera as the red emergency light flickers across her pale face.
