Infografía de alfabeto checo para aprender lenguaje de signos

Card grid infographic titled "Czech Sign Language Alphabet". 9 uniform cards in a clean grid, classroom poster style, friendly primary palette, editorial reference-poster illustration. Each card shows a clear central diagram of anatomically accurate hand positions for a sign-language manual alphabet, with natural finger joints, realistic thumb placement, correct palm orientation, and consistent viewing angle; include subtle motion arrows only if needed for clarity. Each card includes a name IN English and a one-line description IN English. Cover the Czech Sign Language alphabet as a teaching reference, while using the ASL (American) sign system visual forms only if explicitly appropriate; prioritize deaf-community-validated accuracy and educational clarity. Add a small neutral header card or legend card for hand orientation and dominant-hand notes if needed, while keeping all cards uniform and simple. No Spanish text on the image; the visual should satisfy search intent for learning sign language. All text MUST be written in English (array). Every heading, label, caption, legend and metric name in the image must be in English — not English. Spell each English word correctly using English characters and diacritics. Numbers stay as digits, no real brand logos, no watermarks Anatomically accurate hand positions. Verify with deaf-community resources.
