三色等距城市海報模板
奶油紙、黑線稿加一個強調色，等距鳥瞰的復古旅行海報。
✍️ “三色+無漸變”是這類海報能穩住的原因，限制越死，每次換城市的版面越統一。強調色大面積鋪天空，是讓建築線稿保持黑白的小心機。做系列時只換三處變數，一套模板能出一整面牆。

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.
