Alphabet pour les sourds : grille infographique en 12 cartes

Card grid infographic titled "Czech Sign Language Alphabet". 12 uniform cards in a clean grid, editorial reference-poster illustration, minimal flat style, minimal monochrome palette. Each card shows a clear central diagram of an anatomically accurate hand position for a letter of the manual alphabet, rendered with precise finger joints, palm orientation, thumb placement, and wrist angle, optimized for educational clarity. Use the DGS (German Sign Language) fingerspelling system as the visual reference set, while framing the infographic topic as Czech Sign Language alphabet for comparison/learning context. Include cards for letters A, B, C, D, E, F, G, H, I, J, K, L. Each card must contain: the letter name in English, one-line description in English describing the handshape and orientation. Clean spacing, consistent card proportions, high legibility, no decorative clutter, no background distractions. Emphasize verified, deaf-community-informed handshapes and natural anatomy. 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.
