<https://s.mj.run/HcwOEvWbDhA> A vertical, elongated background design for a card flip game inspired by poker cards, with a 16:9 aspect ratio. The design should feature a classic casino ambiance with a green felt texture, commonly associated with poker tables. Incorporate poker card motifs such as hearts, diamonds, clubs, and spades scattered subtly throughout the background. Include elements like poker chips, dice, and gold coins to add a realistic casino feel. The sides should have illuminated borders and ornate gold patterns, enhancing the luxurious atmosphere.
