Create a highly detailed, professional-grade playing card design featuring the King of Hearts. The card should be a front-facing, symmetrical illustration, centered around the majestic figure of the King. Incorporate ornate Baroque-style decorative elements throughout the design, including intricate gold filigree, heraldic crests, and classical architectural motifs in the border and corners. The King should be depicted in traditional royal attire, holding his regalia. Use a rich, luxurious color palette dominated by deep reds, royal blues, and lustrous golds, with subtle hints of emerald green. The overall aesthetic should evoke the elegance and craftsmanship of a vintage, high-quality playing card.
