guess what we have for the very first time this year at FUN OCaml?

Some kind of cards with modern design featuring black backgrounds and beige/tan colored bands across the middle. The cards display names including "Zawiczny" and partial text showing "Dialo" and "ahrefs" branding. Multiple stacks of cards are arranged on a white surface next to a laptop keyboard. The cards appear to have a professional, minimalist aesthetic with white text on dark backgrounds and coordinating tan accent stripes.
