"""站点界面的中英文文案。
只有「网站框架」的部分需要翻译:导航、按钮、页面标题、页脚统计等等。
文档正文(README.md、INSTALLATION.md)、源码里的说明与注释、教程脚本
都保持原样,不在这里翻译——它们是文件内容,不是界面。
站点是静态的,所以不做运行时切换,而是构建时生成两套页面:
* 中文在站点根目录(index.html)
* 英文在 en/ 子目录(en/index.html)
两套页面里的文件引用都相对于各自所在的目录,所以每个语言目录都是自洽的。
新增文案时,zh 与 en 两边都要写;缺哪一边,构建时会直接报错,
免得网站上线后有一半界面还是另一种语言。

"""网站构建脚本的自检:用人造包检验通用性。
人造包刻意与本仓库的 guan 包结构不同,覆盖各种「源码大改」后可能出现的形态:
包一(mypkg)
* 包名不同(mypkg)、目录布局不同(<root>/src/mypkg)
* 元数据写在 pyproject.toml 的 [project] 表里(不是 setup.cfg)
* 函数说明用 docstring,而不是定义上方的注释
* 带类型注解、async 函数、@deprecated 装饰器
* 有嵌套子包(mypkg.sub.extra)
* 有私有函数(下划线开头)与显式 __all__
* 有一个语法错误的文件(构建不能中断)
包二(edge)—— 各种边角情形
* 空文件、带 BOM 的文件、CRLF 换行的文件、GBK 编码的文件
* 文件名不是合法标识符(my-module.py)
* 函数内部再定义函数(不应出现在 API 顶层)
* 类里的 property 与 async 方法
* `from . import helper` 形式的相对导入
* README 里带本地图片、表格、任务列表
* README 与源码里出现 {{version}} 这类模板占位符(不能被替换掉)
包三(empty)—— 什么都没有
* 没有任何函数时,「API 参考」页应当自动消失
用法:

"""读取 tutorials/ 目录,为网站提供「教程」页的内容。
教程内容不手工维护:分组、标题、说明、依赖都从 tutorials/ 下的脚本
与其 README.md 里读出来。仓库里新增一个示例脚本,网站自动跟着更新。
信息来自两处,互相补充:
* 每个脚本开头的注释——标题、来源链接、一句话说明
* tutorials/README.md 里的表格——更详细的说明与依赖说明
两处都没有时,退回到按文件名与 import 推断,保证页面不为空。
