  "PROMPT": {
    "main": "{fruit_name}-themed ultra-realistic yet dreamy commercial beverage photography. A sparkling soda with fruit-derived coloration and gentle translucency, contained inside a clear glass bottle following the resolved bottle reference. The liquid appearance is determined solely by fruit analysis, regardless of the bottle reference image. The bottle is lying diagonally and partially embedded among a moderate amount of clear, solid beverage ice cubes. Ice cubes are smooth, naturally shaped, gently melting, transparent with a clean warm-white appearance, filling the frame without crowding. High-key pastel studio lighting with a clean fruit-inspired color glow, soft warm-white highlights, sparkling highlights, and gentle bokeh light flares. The bottle surface is glossy and fully covered with dense condensation droplets and shimmering water beads. A colorful illustrated label themed around the true local appearance of {fruit_name}, using pastel gradients and decorative dots in a light, high-saturation palette. No muted colors, no gray or brown cast, no crushed ice, no flat lighting, no plain white background, no documentary realism."
