豪華なイスラム幾何学模様の背景と装飾ボーダー

A highly detailed ornamental Islamic geometric background design, elegant and luxurious. The main canvas is a soft beige to light gold gradient with subtle repeating Islamic star and polygon patterns embossed in a slightly darker beige tone, giving a delicate textured look. On the right side, include a vertical decorative border consisting of colorful Persian-Islamic motifs in a repeating pattern: intricate floral medallions with dominant colors of turquoise blue, royal blue, orange, and gold, arranged symmetrically in a vertical strip. This strip should be bordered with thin golden lines. Top-left and bottom-left corners feature symmetrical ornamental corner elements: dark maroon triangular panels with golden edges, decorated with intricate golden floral arabesque patterns extending inward. These corner ornaments should feel embossed, shiny, and luxurious. At the bottom, include a horizontal golden ribbon-like bar stretching across the width, slightly raised with a soft shadow, giving a 3D metallic look. Lighting is soft and even, with gentle shadows to enhance depth. The style is clean, refined, and suitable for a formal notebook cover or certificate background. No text, no people, no objects other than decorative elements. Ultra high resolution, sharp details, vector-like clarity, symmetrical composition, premium design, Islamic art style.
