Generate an SVG as a Thanksgiving greeting card illustration. Dark elegant style. Background fill #100A04. Draw an ornate circular wreath outline — autumn oak leaves, acorns, berries, wheat stalks — in silver (#C8C0A8, stroke-width 0.8) forming a complete ring. Inside, a small geometric pumpkin outline in silver. Radial glow at center in #C8C0A8 (opacity 0.06). Thin double-line oval frame in silver (opacity 0.15). No text, no labels, no emoji. Output raw SVG code only starting with <svg.

The image shows a black background with a white pumpkin in the center surrounded by a laurel wreath. The pumpkin is the main focus of the image, with the laurel leaves surrounding it in a symmetrical pattern.
