Redesign this approved papercraft article cover into a separate EXTRA-WIDE hero banner, EXACTLY about 2.4:1 aspect ratio, ideally 2400x1000. Keep its characteristic tactile paper fibers, folded card volumes, soft natural shadows, mature miniature diorama quality and topic identity. Recompose the artwork for the low-height wide canvas, NOT cropping, squeezing or letterboxing the supplied 3:2 picture. This hero must be clearly related to its thumbnail but use its own complete horizontal composition. All text, subject and watermark must fit with safe margins. Exact readable heading: "Windows 开始使用". Exact understated watermark bottom-right: "clashfreenode.com". No other text. The blue four-window pop-up building, paper stairs, configuration folder and paper planes. Recompose into a wide street-like architectural strip: title on cream paper left, main four-pane building center-right, low stairs sweeping left to right. Avoid a tall tower.
