Auto-generated collage poster prompt for luxury yachts

2x2 grid, 16:9, do this for 4 unusual luxury yachts that are real: input: $ subject, [$move1, $ move2, $ sys1, $ sys2] (optional; else auto‐seed) // phase 1: if movements/systems not given, sample with subject hash. if not provided: moves = random_choice(poster_movements, 2, seed=hash($ subject)) sys = random_choice(graphic_systems, 2, seed=hash($ subject)+1) identity = name_from(moves, sys) // build a compositional field φ that preserves the subject's silhouette and spatial structure. φ = preserve_silhouette( edge_map($ subject) ) // gradient of similarity to original f = ∇φ // flow lines guide typographic grid curl = ∇×φ // rotation informs collage/tear edges div = ∇·f // density maps to halftone/screenprint layers // poster rendering (left half): // - apply movement 1's colour palette and movement 2's texture/print logic. // - graphic systems modulate the build: e.g., if sys1 = "torn paper collage", displace f with tear vectors; if sys2 = "risograph halftone", apply stochastic dot patterns where |div| > threshold. // - typography placed along f streamlines, hierarchy derived from div magnitude. // - authentic ink effects: registration misalignment, paper grain, subtle yellowing. // - silhouette constraint: the subject's outer contour must match $ subject within 92% iou. // right spec panel (dark-grey background): // render high‐contrast white text block: "poster identity: [identity]" and the full instruction copy. // align typography using a swiss modular grid. // combine left and right halves into 2:1 final. render 8k, horizontal.
