    GoutouStdio 站点样式（与 tokens.css 配合使用）
-   分层：基础 → 排印 → 版式 → 页眉 → 页头 → 通用组件 →
-   内容组件 → 终端窗 → 反白带 → 页脚 → 响应式。
-   组件引用 --pg-* token；动效保持正文可读。
+   版式：顶部导航 + 大标题首屏 + 分区正文 + 站点地图页脚。
+   没有动画和装饰图形，层次靠字号、留白和扁平色块。
+   组件只引用 --pg-*，不写死颜色与 4px 以上的尺寸（CI 会检查）。

-          <p>PySpOS 从 2022 年的“MP4 架构狗头 OS”一路迭代到现在：能跑命令、管文件、执行 ELF 程序，应用是独立进程，调度器对标 Linux。3.2.0 是一次内核级重构——1217 行的 <code>main.py</code> 拆成 <code>src/shell/*</code> 包（sys / elf / ota / proc / dispatch），原文件保留兼容 facade；调度在 <code>process.py</code>，进程引擎在 <code>forkexec.py</code>。</p>
-          <p>A/B 双槽位升级：更新装到非活动槽位，校验通过后切换，失败可回滚到上一个版本。命令走元数据注册表，提供分组 help、<code>help &lt;cmd&gt;</code>、Tab 补全，支持管道与重定向；<code>PATH=apps/</code> 下的外部程序可直接执行，<code>cmd &amp;</code> 后台作业配 <code>jobs</code> / <code>fg</code> / <code>bg</code> / <code>wait</code>。</p>
-          <p>ELF 执行默认由 Unicorn Engine 跑真实 x86_64 指令，syscall 转发到内置模拟层；缺 unicorn 时降级到自研 <code>SpaceCPU 1 Pro</code> 模拟器，Windows 也能跑。动态链接（INTERP）与 TLS 还在路线图上。</p>
