 "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).",

 "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 '{argument name="book title" default="THE HOUSEMAID"}' 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: '{argument name="book title" default="THE HOUSEMAID"}' (Large, Yellow, Bold"
