游艇海报，用公式写的拼贴术

Apply the same treatment to four real-world yachts with genuinely unconventional designs, laid out across a 16:9 two-by-two grid. INPUT: $SUBJECT, optional [$MOVE1, $MOVE2, $SYS1, $SYS2] — fall back to an auto-seed when none are given. Stage one, triggered only when movements or systems are missing: IF not provided: MOVES = random_choice(Poster_Movements, 2, seed=hash($SUBJECT)) SYS = random_choice(Graphic_Systems, 2, seed=hash($SUBJECT)+1) IDENTITY = NAME_FROM(MOVES, SYS) Derive a compositional field Φ whose job is holding onto the subject's outline and spatial layout. Φ = preserve_silhouette( edge_map($SUBJECT) ) // how closely it tracks the source F = ∇Φ // the type grid is laid along these flow lines Curl = ∇×Φ // rotation sets the collage tear edges Div = ∇·F // density becomes halftone / screenprint layers Left-half poster render: movement 1 supplies the palette, movement 2 the texture and print logic. Graphic systems steer the execution — say SYS1 = "Torn Paper Collage" shifts F along tear vectors, while SYS2 = "Risograph Halftone" scatters stochastic dots once |Div| crosses the threshold. Typography tracks the F streamlines, its hierarchy set by Div's magnitude. Close with genuine print-shop artifacts — misregistration, paper grain, a hint of age-yellowing. Constraint: keep the outer contour locked to $SUBJECT at no less than 92% IoU. Final render: 8K resolution, landscape orientation.

把同一套处理手法用到四艘真实存在、设计够反常规的游艇上，排布在16:9的2x2宫格里。输入：$SUBJECT，可选参数[$MOVE1, $MOVE2, $SYS1, $SYS2]——都没给时就退回自动种子。 第一阶段，只有在流派或图形系统缺失时才触发： IF not provided: MOVES = random_choice(Poster_Movements, 2, seed=hash($SUBJECT)) SYS = random_choice(Graphic_Systems, 2, seed=hash($SUBJECT)+1) IDENTITY = NAME_FROM(MOVES, SYS) 推导出一个组合场Φ，它的任务就是扛住主体的轮廓和空间布局。 Φ = preserve_silhouette( edge_map($SUBJECT) ) // 和源图的贴合程度 F = ∇Φ // 排版网格顺着这些流线铺 Curl = ∇×Φ // 旋转决定拼贴撕边的走向 Div = ∇·F // 密度转化成半调/孔版印刷的分层 左半边海报渲染：流派1出色板，流派2出纹理和印刷逻辑。图形系统主导具体执行——比如SYS1="撕纸拼贴"会让F沿撕裂向量偏移，SYS2="孔版半调"则在|Div|越过阈值处撒上随机网点。排版沿F流线走，层级由Div的幅值决定。收尾处加上真实的印刷厂痕迹——套印错位、纸张纤维、一点泛黄。约束条件：主体外轮廓必须与$SUBJECT保持不低于92%的IoU重合度。 最终渲染：8K分辨率，横向构图。
