Create a realistic 9:16 UGC-style lifestyle photo of a young adult naturally holding and using the exact same magical color-changing ceramic mug as the provided product reference. The mug must remain 100% identical to the original in every detail—same shape, size, handle, glossy ceramic finish, colors, printed design, typography, artwork placement, proportions, and texture. Do not modify, redesign, recolor, simplify, or enhance the mug in any way. The model is smiling naturally while holding the mug with both hands, with warm coffee inside, looking at the mug as the hidden design magically appears from the heat. The expression should feel genuinely surprised and happy, like a real customer trying it for the first time. Environment: cozy home setting with a clean wooden table, soft morning light coming through a nearby window, blurred kitchen/living room background, realistic everyday lifestyle. Lighting: soft natural daylight highlighting the ceramic texture and the color-changing effect without overexposure. Camera: eye-level smartphone-style UGC shot with a shallow depth of field, keeping the mug perfectly sharp and centered as the main focus. Style: ultra-realistic, authentic user-generated content, natural skin tones, casual clothing, no dramatic cinematic effects. Strict Requirements: The mug must stay exactly the same as the reference. No design changes. No color changes. No added or removed elements. No extra accessories attached to the mug. No text overlays, logos, icons, graphics, watermarks, or borders. Product must remain fully visible and in sharp focus.
