如何在 (Lua)LaTeX 中的对页上手动并行排版文本？

Question

我想使用 LuaLaTeX 在对开页上并行排版双语文本。现有的自动化此任务的解决方案已被证明不令人满意，因为它们不允许脚注（并行），不允许两个并行文本使用不同的字体大小（埃莱德帕尔)，或者通常提供较差的对齐文本块结果 (eledpar)。

由于文本不太长，我真的开始考虑自己分页。为此，我必须解决以下问题：

考虑两页对开页，其结尾段落的长度不同。接下来的段落应该从相同的垂直位置开始，这样这些段落的开头彼此面对。为了实现这一点，

1. 确定页面上较长段落的结尾位置
2. 有办法让下一个平行段落都从所确定的位置开始。

这是可行的吗？ (Lua)LaTeX 是否提供了确定页面上的位置并在页面上的特定位置开始排版的机制？

编辑： 以下示例说明了该任务。此处以“O tempora, o mores”（代码中的第三段文本）开头的拉丁文段落应从段落“Shame on the age...”（第五段）开头的对开位置开始。

我知道这是一个老问题，很长时间没有人关注了。这个话题对我来说非常重要，因为我在大学学习期间用过很多拉丁语文本。

作为一名哲学家和历史学家，我经常使用古代文献的译文，并且总是想知道如何排版它们。我只能想象，如果使用普通的文字处理器，这项任务一定非常艰巨。

由于我确信这是人文学科古典研究部分的许多人面临的主题/问题，因此我想举一个简单的例子来说明reledmacandreledpar包的奇妙可能性。
