"task": "Convert the uploaded reference photo (or a well-known likeness of the named person) into a vintage halftone bold poster-art style portrait illustration.",
  "input": {
    "subject_name": "{{PERSON_NAME}}",
    "reference_image": "{{UPLOADED_PHOTO_OR_NULL}}",
    "note": "Only the subject's name or an uploaded photo should be required from the user. All other parameters below are fixed art-direction rules."
  },
  "output_exclusions": [
    "Do NOT include a small circular/rounded-corner inset photo of the real reference image in the corner of the poster — the final output is the illustration ONLY, full-bleed, no reference thumbnail overlay."
  ],
  "art_style": {
    "medium": "digital illustration mimicking screen-printed / offset-lithograph poster art",
    "influences": ["1960s-70s bold political/protest poster art", "Shepard Fairey-style bold stencil illustration", "risograph print texture", "vintage magazine cover design", "retro concert/album poster art"],
    "line_work": "high-contrast ink linework with fine cross-hatching and stippling for shading, visible pen/brush strokes in hair strands",
    "rendering": "flat color blocking combined with engraving-style fine line shading — NOT photorealistic, NOT airbrushed, NOT smooth gradient shading"
  },
  "composition": {
    "pose": "subject's head and upper shoulders/chest in a strict 90-degree side profile (facing left), eyes looking straight ahead in profile, chin slightly lifted, neutral/confident expression",
    "framing": "portrait orientation (4:5 or 3:4 aspect ratio), subject fills roughly 70-85% of vertical frame, cropped at mid-chest/shoulder",
    "focal_backdrop": "a large solid-color circle (sun/halo motif) centered behind the subject's head, circle diameter roughly 60-70% of canvas width, subject's hair and shoulders slightly overlap and break the circle's edge",
    "hair_treatment": "hair rendered as one of the most detailed elements — individual flowing strands, wind-swept or voluminous movement, strong directional lighting creating highlight streaks within the dark mass of hair"
  },
  "background": {
    "base_texture": "coarse woven linen/canvas paper texture overlaid across the entire composition at low opacity",
    "layout": "asymmetric geometric color-block panels behind/around the circle — e.g. a solid dark rectangle in one lower corner, a contrasting stripe or panel along one edge, sometimes a fine halftone dot-pattern or crosshatch pattern filling one quadrant",
    "halftone_overlay": "visible CMYK-style halftone dot pattern subtly overlaid on background panels and occasionally bleeding into the portrait's shadow areas",
    "grain": "fine analog print grain/noise across the whole image for an aged, screen-printed look"
  },
  "color_palette": {
    "instruction": "Select ONE cohesive limited palette (2-4 colors max) per poster, high contrast, no photographic gradients. Choose based on mood/subject or default to the classic scheme.",
    "classic_scheme": {
      "background_base": "warm cream / aged paper beige (#e8dcc4-ish)",
      "accent_circle": "bold poster red (#c1272d-ish)",

    "alt_scheme_dark": {
      "background_base": "black or deep charcoal",
      "accent_circle": "poster red or burnt orange",
      "linework_shadow": "black ink",
      "highlight": "warm cream/tan"
    },
    "alt_scheme_cool": {
      "background_base": "deep navy blue",
      "accent_circle": "muted brick-red/orange",
      "linework_shadow": "navy/black ink",
      "highlight": "warm cream, with the subject's true eye color kept naturally visible as the one full-color accent"
    },
    "duotone_option": "for a graphic pop-art variant, render the entire subject in a single duotone (e.g. mustard-yellow and black, or gold and black) instead of cream/red/black"
  },
  "typography": {
    "headline": {
      "content": "subject's name (first name, or first+last stacked on two lines)",
      "placement": "top-left corner of the poster, inset from edges",
      "font_style": "extra-bold condensed slab-serif or grotesque sans-serif, all caps, tightly kerned, stacked on 1-2 lines, large scale (dominant typographic element)",
      "color": "matches the linework/shadow ink color, occasionally with a subtle drop shadow or outline for depth"
    },
    "subheadline": {
      "content": "a short 2-4 word tagline/epithet related to the subject (e.g. an evocative title, nickname, or descriptor)",
      "placement": "directly below the headline, smaller scale",
      "font_style": "bold condensed sans-serif or slab-serif, all caps, single line",
      "color": "the poster's accent color (matches the circle color)"
    }
  },
  "clothing_and_accessories": {
    "styling": "simple, era-appropriate or modern minimal clothing rendered in flat color with the same halftone/linework shading as the rest of the piece — collared shirts, blazers, off-shoulder tops, or textured jackets with visible fabric-fold linework",
    "accessories": "keep minimal — small jewelry (earrings, necklace) can be included if present in reference, rendered as simple line-art shapes"
  },
  "lighting": {
    "style": "single hard directional light source (as if raking across the side profile), creating strong graphic shadow shapes rather than realistic soft shading",
    "shadow_rendering": "shadows built from crosshatching, stippling, and halftone dot density rather than smooth gradients"
  },
  "quality_and_fidelity": {
    "likeness": "preserve accurate, recognizable facial proportions and features of the subject from the reference photo/name, translated into the illustrated line-art style — the illustration must be clearly identifiable as that specific person",
    "resolution": "crisp, poster-print-ready quality, sharp linework, no blur, no photographic artifacts",
    "consistency": "maintain identical composition, palette rules, and typography placement described above regardless of subject, so the whole set reads as one unified poster series"
