`body nav:first-of-type` is too restrictive for real-world use cases

[Arcesilas]

Hi,

First of all, thanks for creating Bahunya — I really like its minimal and elegant approach.
However, I’ve run into a limitation with the rule targeting the site navigation:

body nav:first-of-type { ... }

This selector assumes that the first <nav> element in the document is the main site navigation.
Unfortunately, this becomes problematic as soon as you introduce other <nav> elements elsewhere — for example, pagination, article navigation, or table of contents.

Because :first-of-type applies within each parent, not globally within the document, every first <nav> inside a container (e.g. <main>, <aside>) also matches this rule.
As a result, styling leaks to other navs unintentionally.

💡 Suggested improvement

It would be more robust to target the main navigation explicitly, for example: header > nav.

This keeps the classless nature of Bahunya but avoids false positives.

Thanks again for this lovely project — it’s small details like this that can make classless CSS even more versatile!
