    "Cream poster-paper border with the artwork sitting inside a slightly inset field rather than bleeding to the edge.",
    "Loose childlike marker-scribble background blocks, mostly bright sky cyan and sour lime green, with uneven white gaps.",
    "Flat illustration with no realistic depth, no cast shadows, no gradients, and no polished vector smoothing.",
    "Thick imperfect black or dark-brown outlines with variable pressure, rounded ends, and visibly wobbly hand-drawn edges.",
    "One oversized simple subject dominates the lower middle of the poster, with tiny supporting props or characters as scale contrast.",
    "Large hand-lettered headline at the top, irregular baseline, chunky brush-marker shapes, and dense casual spacing.",
    "Small secondary text sits in a corner as a compact block, often over a dark marker swash or rough underline.",
    "Palette is intentionally limited: cream base, cyan field, lime field, dark brown type, black keylines, white character fill, and one or two candy accents.",
    "Decorative grammar uses tiny flowers, grass ticks, curved motion marks, small stars, butterflies, and doodle dots, never dense scenery.",
    "Mood is playful, naive, poster-like, and lightly absurd, with a handmade school-notice energy."

    "Do not include a pink butterfly in the same upper-right placement as the reference.",
    "Do not include signatures, creator marks, platform marks, usernames, watermarks, or QR codes."

  "visual_deconstruction": {
    "style_category": "naive marker poster illustration with public-service announcement hierarchy",
    "composition_logic": "inset poster field with headline-heavy top, huge simplified central subject, sparse supporting doodles, and a small secondary text block near one lower corner",
    "subject_placement": "main subject is very large and simple, cropped or stretched across the center-lower area, while small objects float nearby for humor and scale",
    "perspective": "front-facing flat drawing with almost no perspective; scale is emotional and graphic rather than realistic",
    "typography": "hand-drawn brush-marker lettering, irregular stroke thickness, uneven baseline, dark-brown headline mass, and compact corner microcopy",
    "palette_behavior": "cream paper plus high-saturation cyan and lime scribbles, dark brown headline, black keylines, white fills, and small pastel accent marks",
    "texture": "visible marker strokes, unfinished scribble edges, accidental gaps, simple rough paper feel, and no digital polish",
    "lighting": "flat even color without shadows or dimensional highlights",
    "mood": "playful, handmade, childlike, friendly, and slightly silly"
  },
  "composition": {
    "layout": "Use a cream outer margin, top headline zone, central oversized subject, one small supporting prop or character, sparse doodle accents, and a compact text block near a bottom corner.",
    "density": "Keep the page sparse and readable; avoid filling the background with many objects.",
    "scale": "Make the main subject comically large compared with props, with simple stretched shapes and open negative space.",
    "crop": "Allow the subject to nearly touch the scribble field edges, but keep the cream border visible."
  },
  "typography": {
    "headline": "Oversized irregular hand-lettered marker text, preferably dark brown or black-brown, with rounded brush ends and uneven baselines.",
    "secondary": "Small blocky sans or hand-lettered microcopy in a lower corner, sometimes sitting on a rough dark marker swash.",
    "text_behavior": "Text should feel handmade and imperfect, not typeset, not clean vector lettering, and not a polished logo."

    "base": "warm cream paper",

    "rendering": "flat raster illustration that appears hand-drawn with marker and brush pen",

    "finish": "simple printed poster surface with no 3D modeling, no airbrush, no photo texture, and no glossy effects",
    "resolution_intent": "clean high-resolution raster while preserving handmade irregularity"
  },
  "design_rules": [
    "Preserve the cream border and loose cyan-lime scribble field in every image.",
    "Build the image around one oversized flat subject and one small supporting prop or character.",
    "Use thick wobbly hand-drawn outlines and avoid clean vector-perfect geometry.",
    "Keep the headline large, handmade, dark, and placed in the top zone.",
    "Use only a few small doodle accents so the poster remains sparse.",
    "Keep the message playful and simple rather than commercial or cinematic."
  ],
  "do": [
    "Use irregular marker lettering and chunky brush text.",
    "Let scribble fills spill unevenly and leave small uncolored gaps.",
    "Make the main figure or object simple, white-filled, and outlined with a confident imperfect line.",
    "Keep background details symbolic and childlike: dots, tiny flowers, ticks, sparks, motion lines.",
    "Change the subject, action, text, setting, and story premise for every reuse."
  ],
  "avoid": [
    "No photorealism, 3D render, gradients, polished vector icons, glossy effects, or cinematic lighting.",
    "No dense city scenes, product ad clutter, price stickers, UI elements, or complex perspective.",
    "No exact source text, source date, source action, dog, butterfly placement, or white figure touching grass.",
    "No watermarks, signatures, QR codes, usernames, app marks, or brand logos."

  "prompt_template": "Create a {ASPECT_RATIO} image in the Playful Marker Grounding Poster Style. Subject: {SUBJECT}. Action: {SUBJECT_ACTION}. Prop/Product: {PRODUCT_OR_PROP}. Location: {LOCATION}.

Apply these style rules: cream poster-paper border around an inset artwork field; loose sky-cyan and sour-lime marker-scribble background blocks with uneven white gaps; one oversized flat simple subject dominating the center-lower area; one tiny supporting prop or character for scale; thick imperfect black or dark-brown hand-drawn outlines with rounded wobbly ends; oversized hand-lettered dark-brown headline in the top zone; small lower-corner supporting text over or near a rough marker swash; tiny doodle accents such as flowers, dots, stars, motion ticks, and grass marks; flat even color with no shadows, no gradients, no realistic depth, no polished vector smoothing. Important content rule: match the reference style first, then change the source content. Use new subjects, new scene details, new props, and new text while preserving the style fidelity anchors.
