A vast cavernous starship hangar housing massive interstellar battlecruisers undergoing intense laser repairs. Glowing repair beams cut through dark hull surfaces, holographic diagnostic displays float overhead, dramatic volumetric lighting illuminates the industrial deck, metallic reflections shimmer on polished floors, repair drones hover in the background, sci-fi concept art, cinematic wide-angle composition, deep atmospheric lighting with cool blue and warm orange tones.
