  "prompt": {
    "master_visual_brief": "A high-energy Y2K-inspired editorial collage poster with a strong paper-cut and magazine print aesthetic. The entire image has a tactile paper texture with visible cut edges and layered depth. The theme centers around the city {{CITY_NAME}}. All visual elements, including background imagery, stickers, symbols, typography, and graphic decorations, are culturally and visually inspired by {{CITY_NAME}}. The composition follows a fashion magazine cover logic with dense but controlled information, playful energy, and strong visual hierarchy. The character is designed as a dominant half-body portrait occupying most of the poster.",
    "photography_and_character": "Character: a randomly generated young woman aged approximately 18–25. She is fashionable, attractive, and trendy, with no fixed hairstyle, hair color, facial features, or makeup. Her appearance varies naturally but always remains stylish and visually appealing. Fashion style is Y2K-inspired street fashion with playful silhouettes, layered styling, and trendy colors. Framing is a strict half-body portrait: the image is cropped at the waist or slightly above, and the lower body is not visible at all. Only the upper torso, shoulders, neck, and head are shown. Pose and gesture: the character performs a randomly selected Y2K-style dynamic pose with strong tension and attitude, including expressive arm extensions, angular elbow bends, asymmetrical shoulder twists, or forward-reaching gestures. Body language remains bold, confident, and energetic. Facial expression: the expression is slightly playful and friendly, with a hint of cuteness layered on top of confidence. Subtle smiles, softly open lips, bright eyes, or a relaxed playful look are allowed, while the overall attitude remains fashion-forward and dynamic rather than cute-only.",
    "camera_and_lighting": "Editorial portrait framing with a wide-angle look at close distance, optimized for half-body composition. The camera captures only the upper torso and head, with the lower body fully cropped out of frame. Perspective supports dynamic Y2K poses without distorting facial proportions. Lighting is soft, even, and magazine-style, avoiding harsh shadows. The subject is intended to be cut out and integrated into a paper collage rather than rendered as pure realism.",
    "graphic_design_layout": "Center-focused editorial collage layout. At the top, the city name '{{CITY_NAME}}' appears as the main headline in bold uppercase geometric sans-serif letters. Each letter is placed on an individual colored paper rectangle and arranged in a slight arc. The large half-body character overlaps and partially covers the headline and nearby graphic elements, creating a break-the-frame effect. Surrounding the character are floating paper stickers, speech bubbles, and cut-out graphics inspired by {{CITY_NAME}} culture, including local food, landmarks, symbols, street signs, and iconic objects. The bottom section features a full-width magazine-style collage footer composed of layered paper strips, bold button-style typography, small editorial text blocks, and thumbnail-style graphics.",
    "background_system": "The background is a black-and-white or desaturated urban street scene from {{CITY_NAME}}, such as crowds, architecture, or city textures. Background contrast is reduced and softened with grain so it supports the composition without competing with the main subject. The background is partially obscured by the large half-body character and collage elements and maintains a printed-paper appearance rather than photographic realism.",
    "materials_and_textures": "A consistent paper-based aesthetic across the entire image. Visible paper grain, halftone dots, print noise, and slight ink bleed. All elements appear as physical paper cut-outs layered together. Edges are imperfect and tactile. Stickers, typography, and characters cast subtle shadows to suggest layered depth. No glossy, metallic, or digital materials are present.",
    "composition_and_balance": "Clear and stable visual hierarchy: top city headline '{{CITY_NAME}}', central half-body character (upper torso only), dynamic Y2K-style pose with slightly playful facial expression, surrounding city-themed stickers, and bottom magazine-style collage footer. Strong overlaps between character, typography, and stickers create depth while preserving the established layout."
