Blank White T-Shirt Mockup

Lifestyle product mockup showing a completely blank plain white t-shirt laid flat on a dark work-from-home desk surface. No print, no logo, no text on shirt. Shirt dominates square frame, chest area clean for adding a design later. Add lower-corner props only: closed laptop edge, notebook, calming tea mug, small plant. Direct soft overhead lighting, subtle shadow, modern calm productivity vibe, high contrast, photorealistic ecommerce mockup. No artwork, no existing text, no logo, no brand tag, no person, no hands, no keyboard covering shirt, no props on chest, no props above collar, no dramatic lighting.
