Edit the uploaded photo of the person into a sticker in the {STYLE} look: preserve identity/expression; keep pose/clothing; remove background; flat colors (no photoreal), clean shapes; white 8–12px sticker outline with subtle shadow; background: choose a dark or saturated color that has strong contrast against white (≥4.5:1) and keeps the shadow clearly visible. Square 1024×1024 PNG. Add the caption “{CAPTION}” centered at the bottom in bold sans-serif with clean kerning. No other text/elements; no geometry or face distortions; output one image.

Use two inputs: Image 1 = mask, Image 2 = original photo. The mask is a binary PNG where the target region is pure white #FFFFFF and all other pixels are pure black #000000 (if the colors are inverted, automatically invert the interpretation so the black region is treated as the placement area). Insert {OBJECT_DESCRIPTION} entirely inside the black masked region and modify only pixels within that region; every pixel outside the mask must remain bit-for-bit identical to Image 2. The object must be fully contained by the mask (no bleed or overrun); scale and, if necessary, gently warp the object to fit the region while preserving realistic proportions, perspective, and scene lighting. Match color temperature, exposure, contrast, sharpness, noise/grain, and white balance to the surrounding context; if shadows or reflections are needed, confine them to the masked area. Snap the object to the visual center of the region unless otherwise specified, leaving a subtle 2–4 px inner margin; use high-quality anti-aliasing on the object boundary but do not feather beyond the mask edge. Do not add or alter any content outside the mask (no text, borders, stickers, watermarks, or background changes). Maintain the exact pixel dimensions, aspect ratio, and EXIF orientation of Image 2; output a single PNG of the edited image at the same resolution as Image 2.
