I see lots of conversations about not being able to do things in the header
because the decision is based on the content further down the page. But
often the thing overlooked is that the content has already been queried and
loaded from the db *before* the start of the page.

Therefore it is normally possible to peek ahead (at, for example,
$post->post_content) or even walk through the posts loop (don't forget to
rewind it after) to figure out if the javascript, extra css or whatever is
needed.
