A flat 2D graphic design for a long horizontal panoramic signage banner, ultra-wide aspect ratio 3:1 [image_zdZ5pH.png]. The layout shows a long window pane being wiped clean, isolated template. The left side of the window is dark, dusty, and dirty. In the middle, a clean white vector silhouette of a woman uses a window cleaner tool, wiping away the grime in a smooth motion. On the right, through the perfectly clean glass, a beautiful sunny street corner is revealed. On the sidewalk stands a classic vintage advertising kiosk cylinder (litfaßsäule). The poster on the kiosk clearly displays a modern vacuum cleaner, glossy spray bottles, cleaning tools, and bold text "УБОРКА ПОД КЛЮЧ". Cinematic storyboarding style, high contrast, sharp details, print layout, front view, no mockups --ar 3:1
