Premium Minimal Flat Vector Travel Poster

Premium minimal flat-vector travel poster for [CITY_NAME], 3:4 vertical. Create an airy city scene with large typography-safe negative space in the upper-left. Add [CITY_NAME] and one short elegant English caption matching the city mood. Automatically adapt the background to the city: one iconic primary landmark, local architecture, café culture, transport sign, street lamp, flowers, trees, small decorative details, and calm daily-life moments. Use 3–6 people only, naturally interacting with the city: talking at a café, walking, jogging, sketching, or taking photos. Avoid crowds and avoid a single hero character. Style: Japanese stationery aesthetic, luxury sticker illustration, premium commercial flat-vector poster, clean thin outlines, consistent line weight, flat colors only, no shading, no gradients, no texture. Palette: blush pink, dusty rose, sage green, warm cream, soft beige, muted gray-green. Mood: minimal, elegant, calm, refined, high-end travel postcard and lifestyle branding. No realism, no watercolor, no painterly effects, no photorealism, no dense background.
