Create a 16:9 fantasy card-grid image featuring 12 original zodiac-inspired golden guardians. Arrange the cards in a 4-by-3 grid, four cards per row. Each card should show a different original armored guardian with ornate golden armor, a unique silhouette, a dramatic fantasy portrait pose, glowing cosmic background effects, and an elegant decorative card frame. Add a Chinese label on each card for the corresponding zodiac sign or guardian title, but do not use any real anime, manga, game, or franchise names. Avoid existing protected character designs, recognizable armor designs, logos, and official series typography. The final image should feel like a premium collectible fantasy card set with consistent gold lighting, high detail, and a cohesive 12-card layout.
