Limited-Time Charcoal Tee Drop

[Format] Professional e-commerce product main image, square 1:1, studio apparel advertising style with a single-model hero and deal bands. [Colors] Background is a light grey studio wall; primary accents are a yellow inner keyline frame, a huge yellow paint-brush band near the bottom, and the charcoal-black tee. No frame border beyond the keyline. [Layout] Centre: the male model from the thighs up, pinching the fabric at both shoulders. Bottom third: a broad diagonal yellow brush-stroke band carrying the deadline claim, with a white assurance line beneath and a black coupon pill at the very bottom edge. [Subject] A young white / Caucasian man with short dark hair, wearing a boxy charcoal-black heavyweight pocket tee over a white undershirt, gripping the shoulder seams outward to show the structured drape, neutral expression, even studio lighting. [Headline] On the yellow brush band: "Limited-time deal - only 200 per day" in very heavy black display caps with rough painted edges. Beneath on white: "30-day no-questions-asked returns" in black. Bottom black pill: "Extra $10 off with coupon at checkout" in white. [Badges] No badges; the brush band and pill carry the offer. [Mood] Confident, limited-drop urgency; cool grey studio minimalism charged by the raw yellow brush stroke.
