A dramatic close-up of a cybernetic engineer removing her armored vest to reveal a transparent chest cavity. Inside, a biomechanical heart pulses with amber light — a fusion of muscle, wiring, and rotating turbines. Tubes feed it from rib-mounted micro-pumps. Her arms are sleeved in titanium exoskin, with every joint precisely articulated. The background is dark and smoky, lit only by red emergency lights and the glow from her chest. Macro focus on skin texture, condensation inside the cavity, and fine fiber-optics under the skin.
