复古北美邮票网格

Goal: Create a clean gallery sheet of vintage illustrated postage-stamp designs for an atlas-style North American city collection, presented as collectible UI/export assets. Canvas: Landscape canvas, about 870×653 px, off-white background with generous margins and even spacing. Arrange the stamps in a precise 3-row by 6-column grid, for exactly 18 stamps total. Each city appears as a pair: first a sepia monochrome stamp, then a muted full-color version. Layout: Use three horizontal rows with six stamps per row. Leave wide white space between stamp pairs and rows. Add faint small gray export filename captions under the paired groups, aligned near the lower left of each pair, such as “stamp-export-atlas-north-america-46”, “stamp-export-atlas-north-america-47”, “stamp-export-atlas-north-america-48”, continuing through the visible groups. Stamp design: Every stamp is vertical with cream perforated edges, aged paper texture, thin ornate border, and an oval or arched central illustration window. Put “SOL” in the top-left corner and “100” in the top-right corner of every stamp. At the bottom of each stamp, include a ribbon banner with the city or neighborhood name, then stacked location text below it. Use engraved linework, antique travel-poster composition, soft shadows, and slightly worn ink. Exact stamp count and labels: Include exactly 18 individual stamps in this order, left to right, top to bottom: 1 sepia Boston, Massachusetts, United States with a narrow historic street scene; 2 color Boston, Massachusetts, United States with red-brick buildings and a streetlamp; 3 sepia Charlotte, North Carolina, United States with a cozy storefront street and a “Noda” sign; 4 color Charlotte, North Carolina, United States with colorful buildings, plants, and blue sky; 5 sepia Chicago, Illinois, United States with a vertical “Chicago” theater sign and urban architecture; 6 color Chicago, Illinois, United States with the same theater sign in warm gold and teal tones; 7 sepia Wicker Park, Chicago, Illinois, USA with a storefront facade; 8 color Wicker Park, Chicago, Illinois, USA with an orange-brick storefront and teal sign; 9 sepia Cincinnati, Ohio, United States with a historic market building; 10 color Cincinnati, Ohio, United States with the same market in brick orange, green trim, and sky-blue background; 11 sepia Cleveland, Ohio, United States showing a grand arched arcade interior; 12 color Cleveland, Ohio, United States with teal glass ceiling and warm interior perspective; 13 sepia Dallas, Texas, United States with skyline and a “Deep Ellum” sign; 14 color Dallas, Texas, United States with lively street colors, teal sky, and Deep Ellum sign; 15 sepia Denver, Colorado, United States with a blue bear statue form against a glass building; 16 color Denver, Colorado, United States with a bright blue bear and green glass facade; 17 sepia Des Moines, Iowa, United States with a Tudor-style house; 18 color Des Moines, Iowa, United States with red roof, cream walls, green lawn, and blue sky. Text content: Keep the stamp typography uppercase and vintage serif. Use the customizable collection mark {argument name="stamp currency text" default="SOL"}, denomination {argument name="stamp value" default="100"}, and export caption prefix {argument name="export filename prefix" default="stamp-export-atlas-north-america"}. Preserve the city labels as readable English, but allow the overall series theme to be {argument name="atlas region" default="North America"} and the visual finish to be {argument name="stamp finish" default="alternating sepia engraving and muted full color"}. Visual style: Antique engraved postal ephemera, travel stamp sheet, cream paper, scalloped perforations, subtle drop shadows, fine hatch shading, warm browns, faded inks, muted teal, rust, ochre, brick red, and sky blue. Make the colored stamps look hand-tinted rather than modern digital. Keep all stamps consistent in size and framing. Constraints: Do not add people, logos, watermarks, or extra stamps. The key requirement is exactly 18 stamps in a 3×6 grid, with paired sepia/color variants for the 9 listed places, readable city/state/country labels, “SOL” and “100” on every stamp, and faint gray export filenames beneath the groups.

目标：创建一张整洁的复古插画风格邮票画廊，用于北美城市地图系列，作为可收藏的 UI 或导出素材呈现。 画布：横向画布，尺寸约为 870×653 像素，米白色背景，留有宽裕的边距和均匀的间距。将邮票精确排列为 3 行 6 列的网格，总计 18 枚邮票。每个城市以一对形式出现：第一枚为棕褐色单色邮票，第二枚为柔和的全彩版本。 布局：使用三行横向排列，每行六枚邮票。在邮票对和行之间留出宽阔的留白。在每对邮票组的左下方添加淡淡的灰色导出文件名标注，例如“stamp-export-atlas-north-america-46”、“stamp-export-atlas-north-america-47”、“stamp-export-atlas-north-america-48”，并以此类推至所有可见组。 邮票设计：每枚邮票均为竖向，带有奶油色齿孔边缘、陈旧纸张纹理、精致的装饰边框以及椭圆形或拱形的中央插画窗口。每枚邮票的左上角标注“SOL”，右上角标注“100”。在每枚邮票底部，包含一个丝带横幅，标注城市或街区名称，下方堆叠位置文本。使用雕刻线条、复古旅行海报构图、柔和阴影和略显磨损的墨迹。 精确的邮票数量与标签：按从左到右、从上到下的顺序包含 18 枚独立邮票：1 棕褐色波士顿，马萨诸塞州，美国（狭窄的历史街道场景）；2 彩色波士顿，马萨诸塞州，美国（红砖建筑和路灯）；3 棕褐色夏洛特，北卡罗来纳州，美国（舒适的店面街道和“Noda”标志）；4 彩色夏洛特，北卡罗来纳州，美国（色彩丰富的建筑、植物和蓝天）；5 棕褐色芝加哥，伊利诺伊州，美国（垂直的“Chicago”剧院标志和城市建筑）；6 彩色芝加哥，伊利诺伊州，美国（带有暖金色和青色调的相同剧院标志）；7 棕褐色威克公园，芝加哥，伊利诺伊州，美国（店面外观）；8 彩色威克公园，芝加哥，伊利诺伊州，美国（橙砖店面和青色标志）；9 棕褐色辛辛那提，俄亥俄州，美国（历史悠久的市场建筑）；10 彩色辛辛那提，俄亥俄州，美国（砖橙色、绿色装饰和天蓝色背景的相同市场）；11 棕褐色克利夫兰，俄亥俄州，美国（宏伟的拱形拱廊内部）；12 彩色克利夫兰，俄亥俄州，美国（青色玻璃天花板和温暖的室内透视）；13 棕褐色达拉斯，得克萨斯州，美国（天际线和“Deep Ellum”标志）；14 彩色达拉斯，得克萨斯州，美国（生动的街道色彩、青色天空和 Deep Ellum 标志）；15 棕褐色丹佛，科罗拉多州，美国（玻璃建筑前的蓝色熊雕像）；16 彩色丹佛，科罗拉多州，美国（明亮的蓝色熊和绿色玻璃幕墙）；17 棕褐色得梅因，艾奥瓦州，美国（都铎风格房屋）；18 彩色得梅因，艾奥瓦州，美国（红屋顶、奶油色墙壁、绿色草坪和蓝天）。 文本内容：邮票排版保持大写和复古衬线字体。使用可自定义的集合标记 {argument name="stamp currency text" default="SOL"}、面值 {argument name="stamp value" default="100"} 以及导出文件名后缀 {argument name="export filename prefix" default="stamp-export-atlas-north-america"}。城市标签保留为可读的英文，但允许整体系列主题为 {argument name="atlas region" default="North America"}，视觉效果为 {argument name="stamp finish" default="alternating sepia engraving and muted full color"}。 视觉风格：古董雕刻邮政印刷品、旅行邮票单、奶油色纸张、扇形齿孔、细微的投影、精细的阴影排线、暖棕色、褪色的墨水、柔和的青色、铁锈色、赭石色、砖红色和天蓝色。让彩色邮票看起来像是手工上色，而非现代数字印刷。保持所有邮票的尺寸和框架一致。 约束：不要添加人物、徽标、水印或额外的邮票。核心要求是 3×6 网格中正好 18 枚邮票，9 个列出地点均有棕褐色/彩色配对变体，清晰的城市/州/国家标签，每枚邮票上均有“SOL”和“100”，且组下方有淡淡的灰色导出文件名。
