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: "路由器 开始使用". Exact understated watermark bottom-right: "clashfreenode.com". No other text. Bird-eye miniature paper town network with central radio plaza and wireless arcs, connected neighborhoods stretching horizontally across blue paper ground. Panoramic urban network with green and terracotta houses. Keep tower and wireless symbol modest height and heading clear at upper left.
