復古旅遊海報｜城市宣傳活動視覺

中文：為示範城市製作復古旅遊海報。使用大膽簡化形狀，溫暖復古色彩，粒狀紙張質感，戲劇性風景構圖，地標性建築，清澈天空，懷舊中期海報設計。留出乾淨空間供標題，但不要生成凌亂小文字。

English: Create a retro travel poster for demo city. Use bold simplified shapes, warm vintage colors, grainy paper texture, dramatic landscape composition, landmark architecture, clear sky, nostalgic mid-century poster design. Leave clean space for headline, but do not generate messy small text.

中文：浮水印、亂碼文字、過度HDR、現代建築、商標

English: watermarks, garbled text, over-HDR, modern buildings, trademarks
