Create a festive Eid Mubarak poster. Start with a background that blends warm sunrise colors, from orange to gentle pink, symbolizing hope and new beginnings. At the center, place a glowing crescent moon cradled in a bed of twinkling stars, representing the night sky. Surround this with vibrant illustrations of flowers, traditional lanterns, and abstract geometric patterns, creating a joyful atmosphere. Add the text 'Eid Mubarak' in a bold, elegant font at the center or bottom of the design. The color palette should feature rich golds, silvers, and a spectrum of blues to convey warmth, unity, and celebration. Make sure the design is inviting and universal, suitable for sharing with people of all backgrounds
