Blank White T-Shirt 3D Mockup

Photorealistic 3D mockup render of a completely blank white t-shirt laid in a premium folded-but-front-visible arrangement on a dark matte surface. No design, no logo, no text. The visible front chest panel is large, smooth, and unobstructed for placing a design later. Subtle realistic fabric thickness, collar detail, sleeve folds, soft overhead lighting, minimal shadow, high contrast, clean Shopify product image, square 1080x1080. No printed artwork, no words, no logo, no person, no mannequin, no hanger, no props covering chest area, no excessive wrinkles, no harsh shadows.
