Generate an SVG as a holiday greeting card illustration. Dark elegant style. Background fill #1A0A0A. Draw a poinsettia petal arrangement as a frame border in deep red (#8B0000) fine lines around the canvas edges (stroke-width 0.7). Draw an art-deco 8-pointed star centered in gold (#C9A84C) — alternating long and short rays. Thin ornamental frame lines. Sophisticated holiday. No text, no labels, no emoji. Output raw SVG code only starting with <svg.

The image shows a blue background with red poinsettias and a yellow star in the center, creating a festive and cheerful atmosphere perfect for the Christmas season.
