  "wardrobe": {
    "costume": "Classic red-and-blue Spider-Man suit (Sam Raimi trilogy-style webbed design)",

    "rim_light": "Faint rim/edge light along shoulders and hair to separate subject from the background skyline",
    "color_grade": "Neutral-cool cinematic grade, slightly desaturated blues and grays in the environment, with the suit's red and blue kept rich and saturated as the focal color contrast",
