Now I have full context of every file. The current layout is a fixed full-screen dashboard style that doesn't scroll naturally. I need to restructure it into a normal scrollable page with proper max-width container, vertical sections that flow naturally, and responsive grid layouts suitable for standard browser viewport. Let me rewrite all affected files.

页面已按正常网页尺寸重新排布。主要改动包括：移除了 min-h-screen 固定全屏约束和 fixed 背景，改为 max-w-7xl 居中容器配合正常垂直滚动流；所有组件从紧凑的大屏挤压布局改为带合理 padding 和 gap 的标准 section 分段式排列；三栏区域（目标/架构/系统）调整为 3:5:4 的 12 列网格比例；数据统计和覆盖情况分别用独立 section 隔开，每个卡片都有更宽松的内边距和间距，适合日常浏览器窗口浏览。

Now I have full context. I need to redesign everything as a fixed h-screen dashboard that fits in exactly one viewport - a true "digital cockpit". Every component needs to be much more compact, using flex to distribute vertical space precisely.

Now I can remove the unused components (background-goals, system-cards, footer) since they're integrated into the new layout, or better - keep them but update the page to not use them. Actually, looking at the page, I already removed them from imports. Let me also delete the unused footer component since the footer is now inline:

整个页面已重新设计为严格的 h-screen 单屏布局，所有内容在一个视口内展示完毕，不会出现滚动条。布局从上到下分为：顶部紧凑型标题栏、6 个 KPI 指标卡片行、中间主区域三栏分布（左侧设备接入环形图占 3 列、中间四层架构图占 5 列、右侧告警统计双图表+告警列表占 4 列），底部覆盖统计行（乡镇排名柱状图 7:5 行业进度条），最后一行极简标语。所有组件都使用 flex min-h-0 flex-1 策略自适应分配垂直空间，确保内容不溢出。
