  "task": "Edit Image 1 IN PLACE. Replace ONLY the green-screen areas visible through the car windows and windshield with a photoreal, ordinary daytime city street. Do not regenerate, recompose, or reframe any other part of the image.",
  "image_1_source_to_edit": "Car interior plate, camera outside looking in through the windshield. Two actors in the front seats: man in the passenger seat on the LEFT, woman driving on the RIGHT. Green screen fills all window and windshield areas.",
  "keep_unchanged_from_image_1": [
    "exact camera position, angle, lens, and framing",
    "both actors' faces, skin tone, expressions, hair, and wardrobe -- zero identity drift",
    "car body, dashboard, seats, steering wheel, rearview mirror, window trim, wipers, and all interior geometry -- do not resize, reshape, or move any car part",
    "actors' poses, head angles, and the seatbelt positions",
    "the existing lighting on the actors: a soft KEY LIGHT coming from SCREEN-RIGHT (the woman's screen-right cheek is her brighter side) -- keep each actor's existing light direction and brightness exactly, do not relight or flatten"

  "background_replacement": {
    "environment": "an ordinary, well-kept tree-lined city avenue on a bright sunlit day -- lived-in and pleasant, not abandoned",
    "details": "clean mid-rise buildings with intact windows, mature trees with overhanging canopies lining both sidewalks, utility poles, normal parked cars along the curbs, working street signs, bright sky",
    "light_direction": "STRONG directional sun from SCREEN-RIGHT: the screen-right building faces are warm and clearly sunlit (bright), the screen-left side of the street is in cool shadow, and the sky is brightest toward screen-right. Keep this warm-right / shadowed-left contrast clearly readable EVEN THOUGH the background is defocused -- defocus softens detail, not the light direction.",
    "depth_of_field": "the environment beyond the glass is OUT OF FOCUS / shallow depth of field, softer than the actors, who stay sharp -- the closer buildings, trees, and parked cars just outside the SIDE windows are noticeably defocused, the distant street down the windshield even softer. But it is a bright sunlit day, NOT hazy or flat overcast; keep strong tonal separation between the sunlit right side and the shadowed left side. Nothing in the background should be as sharp as the actors' faces.",
    "framing": "fill exactly the window and windshield shapes visible in Image 1 -- do not extend the city beyond the glass into the car body or pillars"

  "lighting_integration": {
    "windshield_and_glass": "add subtle, physically plausible reflections of the street on the windshield and side glass, brighter on the SCREEN-RIGHT side to match the sun -- faint enough that the actors stay clearly visible through the glass",
    "color_temperature": "match the warm sunlit daylight of the new background to the existing light on the actors so it reads as one shot, not a green-screen key",
    "no_green_spill": "remove any green tint / green edge spill on hair, shoulders, and glass"

  "constraints": [
    "no recompose, no camera move, no reframing, no aspect ratio change",
