{
 "subject": {
 "description": "A vintage racing poster centered on the Mazda 787B Le Mans race car, a low, wide, aerodynamic Group C prototype charging toward the viewer. The car dominates the lower half of the frame with blazing round headlights, the iconic orange and green Renown / Charge livery, and large performance typography layered above it.",
 "mirror_rules": "Not a mirror selfie; no mirroring required. Keep the car facing toward the front-right of the image, with the body stretching from the lower-left toward the mid-right for a dynamic racing angle.",
 "age": "Non-human subject, no age setting",
 "expression": {
 "eyes": {
 "look": "The twin round headlights act as the visual eyes of the machine, staring directly into the lens",
 "energy": "Bright, aggressive, overexposed, with the pressure of a dusk or night racing scene",
 "direction": "Headlights aimed directly at the camera"
 },
 "mouth": {
 "position": "The front intake and low nose create a mechanical facial expression",
 "energy": "Fierce, calm, fast, and predatory"
 },
 "overall": "The image feels as if a race car has burst out of an old magazine cover, carrying victory, engine noise, and aged print texture"
 },
 "face": {
 "preserve_original": "Preserve the Mazda 787B low nose, twin round headlights, green front body, orange cockpit area, Renown livery, and sponsor sticker layout",
 "makeup": "Non-human subject; the visual styling functions like high-contrast makeup: vivid orange-red, deep green, bold white typography, black shadow, and scratched highlights"
 }
 },
 "hair": {
 "color": "Non-human subject; visible black antenna, roofline, and reflective cockpit glass",
 "style": "Streamlined roof and windshield swept backward to create a speed silhouette",
 "effect": "Highlights slide across the windshield and curved body panels, as if cut by track lights and low sun"
 },
 "body": {
 "frame": "Extremely low, wide, ground-hugging Group C race body, with rounded front fenders, a flat nose, and the cockpit sitting toward the upper-right",
 "waist": "The mid-body narrows visually through intersecting green and orange graphic blocks, forming a sharp speed line",
 "chest": "The broad front hood carries Charge, CIBIE, Renown, and other markings, functioning like the car’s chest and power core",
 "legs": "Tires and side skirts are mostly swallowed by shadow, only hinting at the car’s low grip and planted stance",
 "skin": {
 "visible_areas": "No human skin is visible. The visible surfaces are painted bodywork, headlight glass, windshield, decals, intake mesh, and body edges.",
 "tone": "Main colors are saturated orange-red, deep racing green, white typography, and black shadows, against a gray-blue sky and dark tree silhouettes",
 "texture": "The car paint should feel smooth, cold, tight, and slightly waxed to the touch; the poster surface should feel like aged printed paper with creases, scratches, worn white edges, grain, and pressure marks",
 "lighting_effect": "Warm white headlights blow out part of the exposure; low sun or track light cuts across the body and typography from the upper-right, creating starbursts, hard rim highlights, and glossy reflections"
 }
 },
 "pose": {
 "position": "The car enters from the lower-right foreground, the nose close to the viewer, the rear stretching toward the left rear; typography presses down over the sky while small photo panels sit at the bottom",
 "base": "The car is racing along the track at high speed, photographed from a low angle, with barriers and trees pulled into horizontal motion layers",
 "overall": "A forward-charging, victorious commemorative stance, as if the car had just passed the camera at dusk and was frozen into an old poster"
 },
 "clothing": {
 "top": {
 "type": "Race livery and sponsor decals",
 "color": "Orange-red, deep green, white, and black",
 "details": "Large Renown branding, Charge / CIBIE marks, Mazda text on the orange windshield banner, white diamond graphic divisions across the body",
 "effect": "High-saturation vintage race sponsor livery, partially interrupted by glare, shadow, scratches, and print wear"
 },
 "bottom": {
 "type": "Chassis, tires, side skirts, and front intake",
 "color": "Black shadow, deep green front nose, small red-orange reflections",
 "details": "Low intake, mesh grille, ground-hugging side skirts, wheels mostly hidden in darkness",
 "effect": "Heavy, planted, mechanical, and fast"
 }
 },
 "accessories": {
 "jewelry": "None",
 "device": "The race car itself and track environment; three small detail photo frames along the bottom like a magazine or collector-card layout",
 "prop": "Poster typography, performance numbers, Le Mans victory text, vintage scratches, and film-like wear"
 },
 "photography": {
 "camera_style": "Vintage automotive magazine cover, 1990s racing promo poster, film scan texture, commemorative poster with bold graphic typography",
 "angle": "Extremely low camera position, slight upward perspective, close wide-angle distortion on the nose; slight tilt and cropping make the car feel like it is bursting out of the frame",
 "shot_type": "Dynamic close-up motorsport shot, wide-angle feel; the car is sharp in the foreground while the racetrack, hills, and trees compress into horizontal speed layers",
 "aspect_ratio": "Vertical poster format, approximately 2:3 to 3:5, suitable for a magazine cover or phone wallpaper",
 "texture": "Aged printed poster texture, worn edges, white scratches, creases, dust, scan noise, hard contrast, and local overexposure",
 "lighting": "Dusk or low-angle racetrack light, warm white headlights blasting into the lens; hard highlights from the right, gray-blue sky, dark tree silhouettes, and high overall contrast",
 "depth_of_field": "The race car is relatively sharp; background guardrails and trees are slightly motion-blurred and less detailed; typography is crisp and flat over the photographic layer"
 },

 "setting": "High-speed racetrack or Le Mans-style circuit environment with guardrails, distant hills, tree silhouettes, and gray-blue sky",

 "the_vibe": {
 "energy": "Fast, hardcore, mechanical, victorious, with the scream of a rotary engine",
 "mood": "Nostalgic but not soft; gritty, excited, and carrying the emotional residue of an old poster kept for years",
 "aesthetic": "1990s Le Mans racing poster, JDM motorsport culture, vintage print, bold typography, film grain, track memorabilia",
 "authenticity": "Keep imperfections: scratches, creases, worn borders, glare, slight off-center composition, layered text, and old scan texture",
 "intimacy": "Not a clean studio advertisement, but a fan-owned poster that has been touched, folded, pinned, and preserved",
 "story": "It had won the 1991 24 Hours of Le Mans, and now it is charging out of a remembered dusk circuit again, headlights still burning, engine noise not fully gone",
 "caption_energy": "The rotary legend never cooled down."
