3D Ghost Mannequin White T-Shirt Mockup

High-end 3D ghost mannequin mockup of a completely blank white unisex t-shirt, no print, no graphics, no text, no logo. Front-facing invisible mannequin, realistic cotton texture, collar and sleeve detail, open smooth chest area reserved for artwork overlay. Background is a moody self-care nightstand scene: dark wall, soft lamp, book, candle, ceramic cup, small plant, blurred enough to keep focus on shirt. Direct soft studio lighting, subtle drop shadow, scroll-stopping contrast, square 1080x1080. No existing design, no words, no branding, no visible mannequin, no person, no hanger, no folded shirt, no empty blank background, no props over the t-shirt, no harsh dramatic lighting.
