Mystical Blue Light on Dark Stage

minimal abstract cinematic scene of an empty dark stage or tabletop horizon, a soft diagonal beam of cool blue light entering from the upper left and fading into blackness, thin glowing horizontal line across the lower third suggesting a reflective surface edge, subtle mist and haze particles in the air, deep shadows, low-key lighting, atmospheric gradient background, smooth blurred textures, moody studio photography, shallow depth of field, soft focus, high contrast, dark negative space, no people, no objects
