"Generate a highly detailed texture of aged parchment paper, commonly used in ancient maps. The paper should have a worn, slightly crinkled look, with natural yellowish-brown tones and subtle variations in shading. Include faint stains, small tears, and frayed edges to give the impression of age and use over time. The surface should have a rough, organic feel, with visible grain and imperfections, but no text, illustrations, or other elements--just the blank, aged paper texture suitable for creating an old map."
