Prompt
A landscape-format 16:9 digital-painting of an old paper sheet rendered as a background, with the canvas framed horizontally and the paper filling the entire frame so edges meet the long sides and top/bottom crop precisely at the aspect ratio boundary. The central area remains mostly clear for overlay text, occupying the middle third horizontally and center-left slightly warmer for natural reading flow. Visible details include deckled torn edges along the left and right thirds, a pronounced diagonal crease from lower-left to upper-right, and clustered foxing spots in the upper-right quadrant complemented by faint coffee stains in the lower-left third. Surface texture shows fibrous paper grain, soft embossed fibers, and tiny pulp flecks with selective ink bleed and feathered edges around stains. Lighting is soft and even across the plane to reveal shallow relief and subtle shadows in creases without directional highlights. Render as a tactile digital-painting with subtle scanner-style noise and paper fiber brushwork for authentic aged character.
