Papel timbrado A4 clássico azul-marinho e creme

Photorealistic print-ready letterhead template for a generic professional services company, designed to visually represent the Portuguese keyword "papel timbrado".

Realistic stationery mockup lighting, sharp paper texture, elegant editorial composition, no real brands or logos, no extra watermarks beyond the design.
