This whole thing is about scanning *something* in early phase, so if
some rules prevent from using style sheets for something that is really
a stylesheet matter (unless we regard it as a client/server negotiation
issue), change the rules.
If some style sheets require early processing, define a new style sheet
language (it could very much resemble CSS, too). Or introduce an
attribute into <style> that tells the browser to process its content
immediately. Then you would have the responsive img settings in one
<style> element, all the normal CSS in other <style> elements or in
external style sheets. (These approaches have different implications on
non-supporting browsers, of course.)
