Premium Charcoal Knit Fabric Close-Up

[Format] Professional e-commerce product main image, square 1:1, macro fabric-texture style. A near-monochrome charcoal knit carrying one bright brushstroke of type. [Colors] The background is the fabric itself: deep charcoal-black cotton jersey around #26262a filling the entire frame under a soft top light with visible fibre detail. Accent a mustard-yellow brushstroke bar with black icons and characters. No frame border. [Layout] The upper three-quarters stay as pure cloth texture, everything above the band left untouched for a raw zoomed-in feel, pinched into a soft spiral whorl slightly right of centre. A horizontal yellow paint-stroke band crosses the lower fifth, carrying the label line on the left and three icon-word groups to its right, divided by thin strokes. [Subject] No people and no product shot - an extreme close-up of thick black cotton knit fabric with a soft centred fold, showing fine vertical ribbing, scattered fibre flecks and a gentle shadow gradient falling from the top light. [Headline] On the yellow stroke, left side: "Premium Quality Fabric" in heavy black characters with a smaller line "Skin-Friendly, Smooth & Silky" beneath. Right groups, each a small black line icon over a word: "Pure Cotton", "Comfort", "Breathable". [Mood] Tactile, understated and confident; the fabric itself is the hero, with one warm yellow stroke delivering all the quality claims.
