三色等距城市海报模板
奶油纸、黑线稿加一个强调色，等距鸟瞰的复古旅行海报。
✍️ “三色+无渐变”是这类海报能稳住的原因，限制越死，每次换城市的版面越统一。强调色大面积铺天空，是让建筑线稿保持黑白的小心机。做系列时只换三处变量，一套模板能出一整面墙。

Mid-century travel poster, vertical format, with [landmark: [LANDMARK]] of [city: [CITY NAME]] as the hero. Typography first: the name "[city: [CITY NAME]]" sits at the top in bold cream sans-serif, with its local-language rendition set smaller in cream directly beneath. Visual language: minimalist isometric bird's-eye view, ultra-fine hatching, screen-print grain. Hold to a strict three-color palette of cream paper, black technical linework and [accent color: [COLOR]], where the accent fills the entire sky as one flat solid tone and appears again in tiny touches on roofs or streets, never as a gradient.
