Tokyo Geofront Central Tower Rooftop

Create a cinematic dark sci-fi concept art scene of {argument name="location name" default="Tokyo Geofront central tower rooftop"}: an immense cylindrical white-gray industrial tower rising from a vast underground megacity cavern, viewed from a high oblique aerial angle. The tower has a broad circular rooftop platform with concentric rings, panel seams, vents, antennas, small machinery blocks, railings, and weathered modular armor plates. Exactly four massive elevated bridges extend radially from the rooftop in a cross-like layout toward the surrounding city walls, each bridge wide, damaged, layered with pipes and structural ribs. Around and below the tower is a deep vertical abyss filled with countless tiny warm yellow window lights, suggesting an enormous subterranean city shaft. In the background, show a ruined rocky cavern rim and dense decayed industrial districts built into the cliffs, with broken towers, scaffolds, and eroded concrete structures. Use a gritty hard-surface mecha/anime game background style, photorealistic concept art detail, desaturated charcoal and off-white palette, cold ambient light from above, warm pinprick lights below, heavy scale, atmospheric haze, dramatic shadows, no people, no vehicles, no readable text, no logos. Emphasize the rooftop design of the central tower, with intricate believable sci-fi architecture and a monumental dystopian mood.
