复古中世纪旅行海报

Design a vertical retro mid-century travel poster of {argument name="city name" default="[CITY NAME]"} showcasing {argument name="landmark" default="[LANDMARK]"}. Stick to a tight 3-color scheme: cream-toned paper background, black technical line drawing, plus one {argument name="accent color" default="[COLOR]"} accent. Aesthetic: minimalist isometric top-down aerial perspective with very fine cross-hatching and silkscreen print grain. Color rules: fill the entire sky in flat solid {argument name="accent color" default="[COLOR]"}, add small {argument name="accent color" default="[COLOR]"} touches on rooftops or street details. Zero gradients allowed. Typography: large bold sans-serif "{argument name="city name" default="[CITY NAME]"}" at the top in cream, with the city's name in its native language set smaller in cream beneath it.

设计一张竖版复古中世纪旅行海报，展示 {argument name="city name" default="[城市名称]"} 的 {argument name="landmark" default="[地标]"}。严格遵循 3 色配色方案：奶油色纸张背景、黑色技术线条绘图，以及一种 {argument name="accent color" default="[颜色]"} 点缀色。 美学风格：极简主义等距俯视视角，带有非常精细的交叉影线和丝网印刷颗粒感。 色彩规则：整个天空填充平整的纯 {argument name="accent color" default="[颜色]"} 色，在屋顶或街道细节处添加少许 {argument name="accent color" default="[颜色]"} 点缀。严禁使用任何渐变色。 排版：顶部使用奶油色的大号粗体无衬线字体书写“{argument name="city name" default="[城市名称]"}”，下方以较小的奶油色字体标注该城市的母语名称。
