Photorealistic close-up of a golden heavy armor gauntlet resting on a metallic desk inside a starship. The gauntlet features layered gilded plates, intricate mechanical joints, and two bright circular arc reactors embedded in the back of the hand and forearm. Cosmic energy glows from the cores, with white-gold light and crackling electricity tracing along the ridges. The scene is bathed in warm amber spaceship-hangar lighting, with scattered sparks and a softly blurred sci-fi background. Cinematic composition, shallow depth of field, ultra-high detail, 8K realism.
