Create a clean flat vector typography design featuring the text “Eid al-adha Mubarak” in bold black lettering on a plain white background. Use elegant Islamic-inspired serif typography with a strong decorative layout: “Eid” at the top, “al-adha” large and centered in the middle, and “MUBARAK” in small uppercase letters below. Keep the design minimal, balanced, high contrast, and print-ready. No gradients, no shadows, no background elements, only black text on white background. Use a modern festive Eid greeting style, suitable for posters, greeting cards, and social media.
