Ultra-realistic cyberpunk style product close-up, eye-level front view, medium shot composition, the main subject is a tech-themed spade suit card placed vertically. The card is made of dark gray matte metal with subtle wear scratches on the surface, edged with silver reinforced metal trim with purple reflections. Inside the card face are bright pink glowing circuit board traces with circular bright dots at the circuit nodes, and a low-poly crystal texture cyan-blue glowing spade symbol at the center. A thin cyan-blue glowing strip runs along the bottom edge of the card, and a small gold square mark sits at the bottom right corner. The card rests on a dark matte reflective surface with a uniform gradient dark gray background, and faint purple-blue reflections appear on the bottom of the surface. The overall lighting uses cool neon lighting with strong contrast between light and dark to highlight the card's self-illumination, 1:1 square aspect ratio.
