Recreate this fantasy educational poster illustration in a 3:4 aspect ratio with wider framing: Two fantasy elemental mages standing side by side. On the left is a young male mage in light blue robes with electric blue lightning effects (Sodium, Na). On the right is a young female mage in purple and green robes with vibrant green-yellow energy arcs (Potassium, K). In the background are floating neural synapse diagrams and muscle tissue illustrations. In the lower center, a glowing sphere split into blue (labeled 'Na') and purple (labeled 'K') surrounded by a bright green energy ring. At the bottom, a neat white decorative banner with crisp, readable Russian text: «Na⁺ и K⁺ участвуют в проведении нервного импульса и регулируют сердечный ритм». Maintain the exact vibrant, colorful anime/fantasy comic art style, detailed shading, and balanced composition adapted for 3:4.
