Animate this real aurora borealis photograph into a natural, realistic night-sky video. The northern lights should move slowly and organically, with gentle waves and soft shimmering, no sudden motion. Keep the landscape completely static. Add subtle, realistic snowfall with depth: some snowflakes close to the camera slightly out of focus, others far away. Maintain natural low-light exposure, slight digital noise, muted night colors. No cinematic effects, no fantasy glow, no stylization. Looks like real long-exposure camera footage gently coming to life
