Photorealistic Christmas Ornament Mockup

Create one photorealistic square Christmas ornament mockup on a 2000 × 2000 px canvas. Use the identical blank warm-ivory ceramic ornament exactly 1000 px in diameter, positioned at X 500 and Y 430, with its outer edges reaching X 1500 and Y 1430. Keep it perfectly front-facing, upright, circular, symmetrical, and completely unobstructed. Show a woman gently holding the ornament from behind at the lower outer sides. She has neat glossy white almond-shaped nails and cream knitted sleeves. Her fingers and nails may touch only the narrow outer rim and must not cover the printable face. Use a softly blurred evergreen Christmas background with warm golden lights and natural neutral lighting. Do not resize, tilt, rotate, crop, or move the ornament. No artwork, text, logos, watermarks, extra hands, or incorrect fingers.
