โปสเตอร์ตัวอักษรชื่อเมือง

Create a clean, modern typographic travel poster in which the name of the city from the user request becomes the entire composition. Render the city name in giant bold uppercase letters spanning the artwork, then weave that city's authentic landmarks, monuments, bridges, streets, transit, parks, and waterfront scenes into, around, and through the letterforms so architecture and typography interlock while the name stays clearly legible. Use a premium flat vector illustration style: crisp geometric shapes, clean outlines, minimal detail, subtle flat shadows, and four restrained retro hues: midnight blue, aged ivory, dusty crimson, and hazy slate. Scatter small city-true accents — street lamps, trees, clouds, birds, bicycles, trams, or ferries — where they support the design without cluttering it. Keep generous negative space on a clean background with a balanced, centered layout, and make every landmark and vehicle accurate to the chosen city rather than generic. Optionally set a small elegant tagline or nickname beneath the name in minimal typography, exactly as the user words it. Ultra-sharp editorial print quality. No watermark, no brand logos, no photorealism. User request: Lisbon with Tram 28, Belém Tower, tiled facades, and the line 'city of seven hills'
