Blank White T-Shirt Mockup

Lifestyle mockup of a completely blank white t-shirt laid flat on a dark armchair or textured throw in a cozy reading nook. No design, no logo, no typography. Shirt large and centered, clear blank chest area visible for future artwork. Add subtle props near lower corners: open book, headphones, tea mug. Soft natural overhead light, calm introvert/self-care vibe, premium realistic product photography, square 1080x1080 crop. No printed shirt design, no text, no logo, no person, no model wearing shirt, no props covering design area, no clutter, no harsh shadows.
