Monochromatyczne megamiasto sci-fi z czarną dziurą

A vertical cinematic sci-fi cityscape viewed from a very high aerial angle at night, rendered in [monochrome black, charcoal, silver, and cold white]. An impossibly vast futuristic megacity stretches to a hazy horizon, packed with thousands of towering skyscrapers, sharp spires, dense glowing windows, and intricate illuminated street grids. In the center-right foreground, a colossal circular black void resembling [an artificial black hole] is embedded in the city, surrounded by countless bright concentric rings of swirling white light trails forming an accretion vortex disk. Silhouetted skyscrapers border and warp into the gravitational void. Atmospheric volumetric haze, soft bloom, fine structural details, subtle film grain, and a luminous fog band near the horizon. No people, no visible vehicles, no text, no watermark.
