YouTube banner for a channel called "Lukyanov AI". Dark background, dark gray to black gradient. Futuristic tech style with subtle AI / neural network elements (glowing lines, nodes, light particles). No text on the banner — just the visual atmosphere. Space for text in the center or on the left side. Elegant, modern, professional. 4K resolution, 2560x1440 pixels, wide format. No bright colors, monochrome with white and silver accents. No people, no faces.
