404 错误空状态页面

一张 1024px 宽桌面友好型 404 错误/空状态页面截图，浅柔和色调设计。居中布局：上方为可爱扁平风格插画，一位穿宇航服的小宇航员漂浮于粉彩星空与破裂星球间，使用柔丁香紫、桃粉和薄荷绿色调。下方"404"圆角展示字体（深海军蓝），副标题「页面好像走丢了」（中灰），描述段落。两个并排按钮：薄荷绿填充「回到首页」和描边「浏览站点地图」。下方搜索栏「搜索你需要的内容…」。背景近白色带淡紫色渐变边缘，顶部导航栏。整体氛围轻松友好，不令人紧张。

A desktop browser mockup of a friendly 404 error / empty-state page, rendered at 1024 px wide in a light pastel design. Centered layout: at the top a large playful flat illustration — a small astronaut in a spacesuit floating among pastel stars and a cracked planet, rendered in soft lilac, peach, and mint tones. Below the illustration, bold large text "404" in a rounded display font in muted navy, followed by a subtitle "Houston, we lost this page." in medium gray. A descriptive paragraph reads "The page you're looking for was moved, deleted, or never existed." in small body text. Two buttons side by side: a filled mint-green "Go Back Home" and an outlined "Browse Sitemap". A small search bar beneath invites: "Or search for what you need…". Page background is near-white with a subtle lilac gradient at the edges. Navigation bar at top shows a logo placeholder and links. The overall mood is light, friendly, and reassuring — not alarming.
