Lone Woman in Ruined Megastructure

Create a widescreen cinematic science-fiction concept art scene in a bleak monochrome palette. The setting is the colossal interior wreckage of a destroyed futuristic megastructure or crashed spacecraft, viewed from a low ground-level perspective under an enormous dark ceiling slab that dominates the top two-thirds of the frame. Show one lone female figure standing slightly right of center in the distance, small against the architecture, with long black hair, pale skin, and a flowing dark-and-white layered outfit or coat, giving a quiet post-apocalyptic heroine mood. Surround her with shattered metal plates, collapsed floor debris, hanging cables, jagged beams, and broken hull fragments; include three massive curved structural ribs receding into the bright misty opening behind her. Strong backlight floods in from the left and rear, creating a white foggy exterior glow and deep silhouettes in the foreground. Use dramatic scale contrast, sharp angular sci-fi industrial forms, subtle dust haze, high detail, matte-painting realism, cold gray and black tones, no text, no watermark. Aspect ratio 16:9. Optional customization: the lone character is {argument name="character name" default="an unnamed dark-haired woman"}, the environment is {argument name="ruined structure type" default="a crashed alien megastructure"}, the mood is {argument name="cinematic mood" default="bleak post-apocalyptic solitude"}, the color palette is {argument name="color palette" default="cold monochrome gray and black"}, and the lighting is {argument name="lighting style" default="harsh white backlight through fog"}.
