Thanks!
I looked into this again, and I can see that the FAQ entry is dubious.

> +** How can I preserve faces when I export an org file from the command line?

Note that the FAQ entry is talking both about exporting Org files and
also exporting agenda - two different code branches.

And this example is talking specifically about agenda export, which is
relying on htmlize package. There, the css generation is controlled by
`htmlize-output-type', not by `org-html-htmlize-generate-css'.

So, we need a much more significant rewrite to make this FAQ entry up to
date.

[ org-faq is severely outdated, unfortunately. It would really be welcome
  if some kind soul could review it and update things as needed. ]

And in agenda, it will be org-agenda-export-html-style variable that has
to be set.
