16:9, 2x2 grid, do this for 4 intense AI inferred scifi scenes
 input: $ subject // extract the subject as a graphic silhouette. s = silhouette($ subject) f = focal_features($ subject) m = motion_or_emotion_vectors($ subject) // build a monochrome art deco poster world. deco_frame = construct_frame( geometry = ['arches', 'stepped towers', 'vertical skyscraper ribs', 'sunburst panels', 'circular medallions'], symmetry = 'semi-symmetrical', border = 'thick black ornamental frame', density = 'high but readable' ) // convert subject into hard black-and-white vector forms. subject_graphic = vectorize( s, style = 'art deco noir', line_weight = 'thick outer contour + medium internal lines', fill_logic = 'pure black, pure white, limited gray', surface_detail = 'angular panels, clean shadow blocks, elegant negative space' ) // rebuild details using architectural language. detail_system = remap(f) where: - curves become elegant deco arcs and streamlined contour bands - small repeated details become windows, vents, stripes, grids, geometric ornaments - organic textures become clean black-white pattern fields - motion becomes diagonal speed lines, fan rays, stepped echoes, or theatrical silhouettes // background becomes a symbolic metropolis. city_field = generate_cityscape( from = m, shapes = ['tall towers', 'bridges', arches', 'clock faces', 'abstract machinery', 'ornamental facades'], color = 'black and white', perspective = 'poster-flat with selective depth' ) render: - $ subject is central, elegant, dramatic, and poster-readable. - use hard black/white contrast with tiny gray accents only where needed. - add art deco architecture around and through the subject. - use vertical rhythm, arches, stepped geometry, clean negative space, and theatrical noir staging. - no photorealism, no color, no painterly softness. - final image feels like a premium 1930s noir city poster redesigned as modern vector art.
