遊艇海報，用公式寫的拼貼術

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.

把同一套處理手法用到四艘真實存在、設計夠反常規的遊艇上，排布在16:9的2x2宮格里。輸入：$SUBJECT，可選引數[$MOVE1, $MOVE2, $SYS1, $SYS2]——都沒給時就退回自動種子。 第一階段，只有在流派或圖形系統缺失時才觸發： IF not provided: MOVES = random_choice(Poster_Movements, 2, seed=hash($SUBJECT)) SYS = random_choice(Graphic_Systems, 2, seed=hash($SUBJECT)+1) IDENTITY = NAME_FROM(MOVES, SYS) 推匯出一個組合場Φ，它的任務就是扛住主體的輪廓和空間佈局。 Φ = preserve_silhouette( edge_map($SUBJECT) ) // 和源圖的貼合程度 F = ∇Φ // 排版網格順著這些流線鋪 Curl = ∇×Φ // 旋轉決定拼貼撕邊的走向 Div = ∇·F // 密度轉化成半調/孔版印刷的分層 左半邊海報渲染：流派1出色板，流派2出紋理和印刷邏輯。圖形系統主導具體執行——比如SYS1="撕紙拼貼"會讓F沿撕裂向量偏移，SYS2="孔版半調"則在|Div|越過閾值處撒上隨機網點。排版沿F流線走，層級由Div的幅值決定。收尾處加上真實的印刷廠痕跡——套印錯位、紙張纖維、一點泛黃。約束條件：主體外輪廓必須與$SUBJECT保持不低於92%的IoU重合度。 最終渲染：8K解析度，橫向構圖。
