Create a clean 2D minimalist YouTube channel icon featuring a central abstract node symbol (simple geometric network node, modern and tech-inspired). The node should be centered, medium-sized, with smooth lines and subtle glow. No text at all. Use a vibrant, eye-catching blue background (electric or neon blue) with slight gradient for depth. Flat design, high contrast, visually striking, recognizable at small sizes, идеально for a profile picture. Ultra sharp, modern, minimal, no clutter.
