邮政几何建筑邮票生成指令

2x2 grid, 16:9, do this for 4 stamps of different countries and eras: INPUT: $ COUNTRY, optional $ ERA Φ   = correspondence_culture_field($ COUNTRY, $ ERA) F   = ∇Φ     // pen strokes, folding paper, the walk to the postbox Curl= ∇×Φ    // wax-seal swirls, twine loops, postmark rings Div = ∇·F    // density of ink, stamps, paper, sealing tools GATES = select_four(Φ, [AI infers']) // Per gate derive: Room Architecture, Signature Furniture, Writing/Sending Ritual, //   View Outside, Postal Object Type, Material Palette, Time of Day. // POSTAL GEOMETRY RULE: //  - Perforated stamp → serrated-edged room; perforations = wall pillars; the printed vignette = the window mural. //  - Wax seal → a domed vault; the seal impression = ceiling relief; the ribbon = a stair rail. //  - Meter / frank mark → a grid-modular post office; the franking bars = structural beams. //  - Twine + shipping tag → a suspended parcel-house; the twine = rafters/rigging; the tag hole = the doorway.

2x2 网格，16:9，针对 4 枚不同国家和时代的邮票执行此操作：输入：$ 国家，可选 $ 时代
Φ = 通讯文化场($ 国家, $ 时代)
F = ∇Φ // 笔触，折叠纸张，走向邮筒的过程
Curl = ∇×Φ // 火漆印漩涡，麻绳环绕，邮戳环
Div = ∇·F // 墨水、邮票、纸张、密封工具的密度
GATES = select_four(Φ, [AI 推断']) // 每个门派生出：房间建筑、签名家具、书写/寄送仪式、窗外景色、邮政物品类型、材料色调、一天中的时间。
邮政几何规则：
- 齿孔邮票 → 锯齿边缘的房间；齿孔 = 墙柱；印刷插图 = 窗户壁画。
- 火漆封蜡 → 圆顶拱顶；封印压痕 = 天花板浮雕；丝带 = 楼梯扶手。
- 邮资机印 / 邮资戳记 → 网格模块化邮局；邮资条纹 = 结构梁。
- 麻绳 + 货运标签 → 悬吊的包裹屋；麻绳 = 椽子/索具；标签孔 = 门口。
