A single bionic prosthetic right arm, isolated, no body, no torso, no head — just the arm from shoulder to fingertips. Sleek matte-white armor shell panels over the upper arm, forearm and hand, with exposed dark gunmetal-grey articulated joint mechanisms at the elbow and wrist. Five fully articulated mechanical fingers with segmented phalanges and visible knuckle joints, plus an opposable thumb. High-end cybernetic prosthetic aesthetic, clean and seamless. Straight neutral pose, arm extended, fingers slightly relaxed. Plain background, single object.complete solid arm, rounded capped shoulder, long slender fingers, clean closed mesh, no gaps
