Miniaturka Kursu Produktów AI

Polished promotional hero graphic for an online course on commercial AI product visuals. In the center, a premium blank [t-shirt] floats in midair as a realistic 3D product mockup with smooth fabric texture, short sleeves, rounded collar, and no logos. The background is a dark navy-to-charcoal gradient with a subtle floor reflection and soft vignette. Studio lighting features a warm golden rim light from the left and cool electric blue fill from the right. The product is surrounded by glowing golden circuit-board traces, luminous nodes, and scattered bokeh particles. Floating around the product are 3 semi-transparent dark glassmorphism code-terminal windows with rounded corners and faint monospace code; the upper-left terminal window displays the header "$ prompt engineering terminal". At the bottom center, clean modern typography displays the title "[ChatGPT]" in bold white, with the subtitle "[Foundations]" in warm gold below it. High-resolution commercial tech render, clean negative space, no watermarks, no people.
