## Prompt

```text
{
  "meta": {
    "aspect_ratio": "9:16",
    "quality": "ultra_photorealistic",
    "resolution": "8k",
    "camera": "iPhone 15 Pro Max (Main Lens)",
    "style": "Physical Trompe-l'œil, hyper-realistic photography, accurate scale and depth, no CGI look"
  },

  "scene": {
    "location": "Home interior, hallway/living room",
    "lighting": {
      "type": "Mixed lighting: Overhead recessed warm LED + soft ambient fill from side",
      "effect": "The overhead light creates a bright catchlight in the living eye and casts realistic, soft shadows inside the physical keyhole opening and under the book."
    },
    "background": "Neutral walls, white ceiling molding, dark window blinds in background left, framed art on right, all slightly out of focus"
  },

  "illusion_mechanics": {
    "concept": "Physical Die-Cut Hole & True Depth",
    "description": "The book cover is NOT a flat image. It has a physical, die-cut hole in the exact shape of the brass keyhole graphic. Through this physical opening, the viewer sees the actual, living right eye of the person holding the book.",
    "depth_perception": "The keyhole has visible thickness (the cardstock of the cover). The living eye is set back from the cover plane by a realistic distance (approx. 1-2cm), creating a genuine sense of looking *through* an object to the person behind it."
  },

  "subject": {
    "visible_features": "Long wavy honey-blonde hair with highlights, hands holding the book, school uniform.",
    "outfit": "Dark navy cable-knit cardigan, white button-up shirt, plaid tie (navy, grey, yellow stripes).",
    "the_eye": {
      "type": "Living human eye (anatomically accurate right eye)",
      "characteristics": "Wet sclera with subtle capillaries, complex iris pattern (hazel/brown), dilated pupil, visible blood vessels, realistic eyelashes.",
      "scale_and_proportion": "The eye is positioned and scaled precisely as if the book is pressed against the brow bone. It fills the keyhole naturally and anatomically correctly, without distortion.",
      "lighting_interaction": "The eye is lit by the room's light. A sharp, realistic catchlight from the overhead LED is visible on the cornea. The edges of the keyhole cast a soft, realistic shadow onto the skin and eyelid surrounding the eye."
    }
  },

  "prop_specifications": {
    "object": "Paperback book '{book_title}' by Freida McFadden",
    "orientation": "Vertical, held flat in front of face. The image is a mirror selfie, so all text and the cover art are horizontally flipped.",
    "cover_details": {
      "material": "Matte cardstock with slight texture and wear on corners.",
      "background": "Deep blue with wood-grain texture.",
      "keyhole_frame": "The antique brass frame is printed on the cover, but the hole inside it is physically cut out.",
      "text": "All text is mirrored and legible: '{book_title}' (Large, Yellow, Bold"
    }
  }
}
```
