A flat 2D graphic design for a long horizontal panoramic signage banner, ultra-wide aspect ratio 3:1 [image_zdZ5pH.png]. The layout portrays a panoramic window being cleaned, isolated on a clean print template. On the left, the glass is heavily layered with photorealistic dust, dirt, and water streaks. In the center, a minimalist white silhouette of an elegant woman wipes the glass with a squeegee, leaving a flawless, crystal-clear stroke. Through the clean glass on the right, a bright sunny modern city opens up. In the foreground of this cityscape, there is a stylish contemporary building featuring a sharp, highly visible signage that reads "УБОРКА ПОД КЛЮЧ". Cinematic perspective, rich depth, high contrast, commercial print-ready template, front view, no mockups, no environment --ar 3:1
