  "color_theme": "",

  "scene": {
    "hero": "The specified product standing centred on a polished silver serving platter, presented as if it were a dish. A thin glossy pool of syrup or nectar spreads around its base on the plate, with a single fresh fruit garnish laid beside it, cut-side up and glistening.",
    "action": "A cloche — a domed polished silver cover — is being lifted away, caught mid-motion above the plate, tilted at an angle so its concave underside catches the light and mirrors the scene below. The reveal is the whole idea.",
    "hands": "Two bare female hands enter the frame from the right edge — one from above gripping the cloche handle, one from below supporting the platter from underneath. Slim fingers, natural short nails, a few delicate thin gold rings. Skin softly lit and warm-toned. No arms beyond the wrist, no face, no body.",
    "surface": "Nothing solid — the platter is held aloft in mid-air with no table or support visible",
    "background": "Floor-to-ceiling heavy linen or raw silk drapery hanging in soft vertical folds, filling the entire backdrop, slightly out of focus"
  },

  "composition": {
    "framing": "Vertical 4:5, medium product still life",
    "camera_angle": "Straight-on at platter height, dead level, no tilt",
    "subject_placement": "Product dead centre on the plate, cloche floating directly above it in the upper half, hands anchoring right of centre",
    "negative_space": "Generous curtain field to the left and above",
    "depth": "Three shallow planes — hands and platter foreground, product mid, drapery softly dissolved behind"
  },

  "lighting": {
    "quality": "Warm directional daylight through a window, softly diffused",
    "direction": "Raking side light from frame right, skimming across the drapery folds to create long soft vertical shadows and catching the metal",
    "shadows": "Soft-edged, warm, deep in the curtain pleats",
    "highlights": "Liquid specular sweeps across the domed cloche and platter rim, wet glint on the syrup pool and fruit, gentle glow on the skin",
    "mood_of_light": "Golden, intimate, appetising — luxury editorial rather than clinical product"
  },

  "color_and_tone": {
    "grading": "Warm, softly saturated, gently lifted shadows. Creamy highlight roll-off, no crushed blacks.",
    "contrast": "Medium, smooth gradients"
  },

  "technical": {
    "camera": "Medium format digital, 85–100mm equivalent",
    "aperture": "f/4 — product tack sharp, drapery softly rendered",
    "focus_point": "The product label and the fruit garnish",
    "texture": "Immaculate clean render, crisp detail on metal and skin, very fine grain, no vignette"
  },

  "notes": "Absolutely no text, lettering, captions or typography anywhere in the frame.",

  "style": {
    "genre": "Luxury product still-life advertising",
    "references": "Modern fragrance campaign, fine-dining reveal staging, warm editorial commercial photography",
    "mood": ["warm", "sensual", "playful", "premium", "appetising", "theatrical"]
