She wears an advanced combat exo-armor suit with a closed system for breathing, complete with a sleek sci-fi helmet featuring a glossy transparent visor and cinematic lighting on the face. The setting is a highly detailed interior reminiscent of "The Expanse" TV series, with vibrant neon and volumetric lighting. The scene captures the intricate textures and natural reflections, showcasing her streamlined figure, shaded hair tail, and bare neck under a blinding light.
