A flat 2D graphic design for a long horizontal panoramic signage banner, ultra-wide aspect ratio 3:1. A minimalist infographic storyboard titled "The Evolution of Cleanliness", isolated on a solid matte graphite-black background. From left to right, a sequential row of 4 sharp, clean white and neon-blue vector icons: 1st icon is chaotic messy dirt splatters; 2nd icon is a simple classic wooden broom; 3rd icon is a high-tech modern vacuum cleaner; 4th icon is a glowing minimalist key symbol. A thin horizontal laser line connects all icons like a timeline. At the far right, next to the key, elegant modern typography text perfectly reads "УБОРКА ПОД КЛЮЧ". Clean vector art, high contrast, commercial print-ready template, front view, no mockups, no environment --ar 3:1
