怎麼填變量：換城市時，[街景]、[街道元素]、[地標] 三處一起改，寫當地人真正熟悉的東西（成都寫"玉林路、茶館、蓋碗茶、火鍋店"）。標題用英文大寫最穩，中文副標題放底部小字。[配色] 只給一組"墨色 + 底色"，例如"磚紅配米白"。

常見問題：

• 招牌字亂碼：畫面裏的中文招牌很難全部正確，可以改成"招牌只出現模糊的色塊，不出現可讀文字"。
• 變成彩色插畫：重複強調"只用一種墨色"。
• 地標畫錯：AI 對小眾地標不熟，越有名越準；不確定就只寫街道氛圍，不寫具體地標。

適合：城市文旅宣傳、門店裝飾畫、個人旅行紀念。

Create a 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.

MAIN COMPOSITION:

Central composition features Istanbul’s most iconic everyday urban scene — a lively tram street in Karaköy, Kadıköy, Beyoğlu, Eminönü, or a Bosphorus-side pedestrian avenue filled with daily life.

Foreground includes local residents, commuters, ferry passengers, café visitors, simit sellers, students, cyclists, street musicians, and shoppers naturally interacting within the city.

People should authentically reflect modern Istanbul street fashion, layered urban lifestyle, and contemporary Turkish culture.

Background filled with authentic Turkish signage, tea houses, bookstores, tram lines, ferry terminals, cafés, bakeries, fish restaurants, street lamps, mosques integrated into skyline, apartment façades, hanging laundry, cats, seagulls, and dense architectural textures.

Subtle landmarks blend naturally into daily life rather than dominating the composition — Galata Tower, Bosphorus ferries, nostalgic tram, mosque silhouettes, and waterfront railings should appear integrated into the urban rhythm.

Use authentic Turkish typography and culturally recognizable street elements.
