Cinematic Sci-Fi Orbital Megastructure

Create a cinematic sci-fi film sequence in a vast abandoned orbital megastructure above a blue planet. A lone astronaut-explorer in a sleek graphite pressure suit walks slowly across a reflective obsidian floor, helmet visor glowing faintly with interface light. 0–4s: Establishing ultra-wide shot. The explorer appears tiny beneath enormous curved alien architecture, floating debris drifting outside panoramic windows, cold starlight cutting through volumetric haze. Camera performs a slow dolly forward with subtle tilt up. 4–9s: Medium tracking shot from behind as the explorer walks toward a dormant circular gate. Floor panels illuminate one by one beneath each step, soft mechanical pulses echo through the chamber. Reflections ripple across the suit, realistic gravity and weight. 9–13s: Close-up on the helmet visor. The explorer stops, raises one gloved hand, and the visor reflects a massive star map forming in the air. Slow push-in, shallow depth of field, cinematic lens breathing. 13–15s: Hero wide shot. The circular gate opens into a blinding white-blue horizon, silhouettes of impossible structures visible beyond it. The explorer stands centered, cape-like survival fabric moving gently in artificial wind. Style: ultra-cinematic blockbuster sci-fi, anamorphic 35mm lens, deep blue and silver color palette, practical glowing panels, volumetric fog, high contrast rim lighting, realistic metallic textures, premium VFX realism, clean spatial audio with low mechanical hums, distant atmospheric rumbles, no music.
