Dark Luxury Heraldic Emblem with Royal Cobra AI Image Prompt

Create a dark luxury heraldic emblem featuring {argument name="animal subject" default="a royal cobra"} centered on a wide horizontal canvas. The cobra faces forward with its hood fully spread, coiled body at the bottom, glossy black scales edged in reflective metallic gold, a golden segmented belly, intense glowing eyes, and a black forked tongue. Place exactly 1 ornate gold crown on the cobra's head and exactly 1 small black-and-gold shield crest below the neck, showing a tiny crowned cobra symbol. Surround the cobra with an elaborate symmetrical baroque frame: exactly 1 large circular gold arch behind the head, 2 mirrored large gold acanthus-leaf flourishes at the lower left and lower right, 2 mirrored vertical side ornaments with black diamond gemstones, and 4 ornate gold corner decorations connected by a thin rectangular gold border. Use a {argument name="color palette" default="black, metallic gold, and deep bronze"} palette with high contrast, polished 3D metal rendering, dramatic rim lighting, sparkling gold dust accents, and a dark textured damask background. The mood should be {argument name="mood" default="regal, dangerous, and opulent"}. Make the composition perfectly centered and symmetrical, ultra-detailed, sharp, cinematic, premium fantasy insignia style, with no text, no watermark, and no extra animals.
