Create a 9:16 minimalist ultra-high-resolution travel poster in line-art style for ISTANBUL, portraying the city as a stylish everyday urban scene rather than a tourist postcard. Center the composition on a lively Istanbul tram street in Karakoy, Kadikoy, Beyoglu, Eminonu, or a Bosphorus-side pedestrian avenue filled with daily life. Include local residents, commuters, ferry passengers, cafe visitors, simit sellers, students, cyclists, street musicians, and shoppers interacting naturally. Show modern Istanbul street fashion, layered urban lifestyle, and contemporary Turkish culture. Fill the background with authentic Turkish signage, tea houses, bookstores, tram lines, ferry terminals, cafes, bakeries, fish restaurants, street lamps, mosques integrated into the skyline, apartment facades, hanging laundry, cats, seagulls, and dense architectural textures. Blend subtle landmarks naturally into daily life, including Galata Tower, Bosphorus ferries, nostalgic tram, mosque silhouettes, and waterfront railings. Use authentic Turkish typography and culturally recognizable street elements. Add large centered title “ISTANBUL” at the top and bottom subtitle “Türkiye” or “İstanbul”. Use ultra-clean vector illustration, Swiss modernist travel poster aesthetic, minimalist monoline line art, mid-century editorial illustration, architectural illustration, contemporary Turkish graphic poster design, crisp geometric perspective, clean negative space, premium luxury travel-brand mood, and highly organized visual density. Use monochrome line illustration only: one primary ink color and one background color, preferably deep Bosphorus navy ink on warm cream background. Use thin precise lines, minimal fill, intricate city-map-level details, rhythmic tram cables, balconies, ferry rails, windows, signage, cats, street furniture, and waterfront architecture. Keep typography clean, readable, professionally designed, and editorial-grade with no random symbols or broken letters. Make the output print-ready, vector-quality, and museum-quality.
