3D Miniaturstadt-Feiertagsszene

Create a clear, isometric 3D miniature cartoon scene at a 45-degree top-down view, depicting the classic architecture or landmarks of [City], and place it at the exact center of the composition. Decorate the city with ornaments, twinkling lights, and appropriate seasonal (default: winter) or festive details matching the [Holiday] theme, making it feel full of holiday spirit. Use soft, detailed textures, realistic PBR materials, and soft, realistic lighting with subtle shadow effects. Build a small diorama-style city base with clean edges. Use a clean [Holiday] background color that contrasts well with the scene. At the top center, display the text [City] in bold, large letters. Directly below it, display "[Holiday] Special Edition" in medium font. (Optional) Place a small square flag icon below the text. All text must automatically match the background contrast (white or black). Composition: perfectly centered, 1080x1080 square, ultra-clean holiday diorama aesthetic.
