Thanks, guys. I think I was over-thinking this. I've decided to do this with pure Javascript included on every page, just giving focus to the first non-disabled input element. Igor's comment about metadata made me realize I was already tagging invalid fields with "invalid" in the class attribute, so I keyed off that to give those fields priority. I also use the CSS class name "nofocus" to avoid always giving focus to a search input at the top of each page.
I've attached the JS if anyone's interested. It won't give focus to a
select or textarea, but I don't need that just now.
