   Every rule the page needs. There are no style attributes in the markup and
   no inline <style> block, which is what lets the CSP run without
   'unsafe-inline' — an injected style= simply does not apply.

   Sections follow the page order: tokens, base, layout primitives, then one
   block per section of the page.
