3D Ghost Mannequin T-Shirt Render

High-quality 3D ghost mannequin render of a blank white t-shirt, front view, no artwork, no logo, no text, no branding. Shirt floats naturally on invisible torso with realistic cotton folds and a large open chest area for design overlay. Relevant background: dark walnut desk scene with coffee mug, notebook, reading glasses, small plant, softly blurred and positioned behind/lower edges so the shirt remains dominant. Warm overhead/front lighting, subtle shadow, scroll-stopping contrast, 1080x1080 square. No printed shirt design, no words, no logo, no visible body, no hanger, no folded mockup, no empty studio background, no props in front of chest, no dramatic shadows.
