Create ONE original realistic square high-resolution production color texture, not a photo of a sample or a presentation. Perfectly orthographic straight-on, one planar material filling every pixel edge to edge. Uniform neutral diffuse lighting, spatially even exposure, sharply resolved full-field detail. Make both opposite edge pairs genuinely seamless with matched structure, scale, brightness and pattern phase. No frame, margins, borders, sample silhouette, cast shadows, vignette, broad highlights, perspective, blurred seams, mirrored quadrants, props, labels, text or watermark. No grids or multiple panels. Native 2048x2048 if supported. Flat uncoated recycled kraft paper: thin compressed cellulose sheet, finely resolved irregular pulp fibers lying flat in random directions, sparse tiny darker recycled-paper flecks, natural subdued buff-tan tone. Intended field20cm across; fibers fractions ofmillimeter to a fewmillimeters. Dense compact matte sheet, not fabric or fluff. No printing or text fragments, stains, folds, tears, deckleedges, leathergrain, parchmentburnededges, cardboardcorrugation, decorativegrunge or featureless tan noise.
