Create a high-resolution seamless texture of a clean white sheet of paper, square format (1:1, target resolution 4480x4480 pixels). The texture should be a flat top-down scan of pure white to off-white paper with fine natural fibrous grain, subtle organic tooth and micro-relief, extremely light and evenly scattered tiny specks/inclusions, no wrinkles, no folds, no shadows on edges, uniform soft even lighting across the entire surface with no vignette. Neutral bright white tone, high detail, photorealistic paper fiber structure suitable for use as a background or overlay texture. Reference the uploaded paper samples for realistic fiber and speckle detail, but keep the result cleaner and brighter (pure white, not gray).
