Generate a dystopian cityscape illustrated entirely as scalable vector graphics (SVG). Build the scene with layered groups of vector shapes: tall, blocky megastructures composed of rectangles and paths with crisp strokes; windows rendered as small repeated rectangles or rounded rectangles with a subtle inner glow. Implement a dominant cold palette—slate gray, iron blue, and electric cyan accents—using linear and radial gradients to convey depth and artificial lighting. Include a high-contrast horizon with a grid of surveillance lines across the sky, formed by thin strokes and semi-transparent overlays to imply omnipresent monitoring. Add a maze of elevated walkways and billboards, their signage outlined in bold strokes and filled with clipped gradients. Keep texture abstract through subtle opacity shifts and a fine stipple pattern created by shape opacity rather than bitmap textures. Ensure the composition uses a tight viewBox, clear layering order, and scalable silhouettes so the scene remains legible at small sizes. Export as a single SVG file with reusable symbols for repeated elements.

The image shows an animated cityscape with tall buildings, a bridge, and a sky in the background. The buildings have windows and lights, giving the image a futuristic feel.
