Cyber Defense BG 04 - Alien Megastructure

Generated from: Vertical portrait 9:16 game background plate, sci-fi cyber-noir. Colossal alien megastructure: towering black angular monolith silhouettes and a distant colossal arch ring on the horizon, thin cyan and pale green energy seams glowing faintly along their edges, drifting dust haze, sparse stars. Very dark, low contrast, silhouettes almost merging into a deep black sky with only faint rim highlights. Structure mass and horizon line sitting in the central upper two-thirds of the frame; bottom 20 percent of the image is near-solid black ground with no detail; left and right edges simple dark silhouettes safe to crop. No text, no logos, no watermark, no characters, no creatures, no vehicles, no UI, no HUD, no frames, no borders. Matte painting, cinematic, subtle grain.
