/* Site header only — the header/hamburger rules from mobile.css, scoped to
   the site header (body > header). Loaded instead of mobile.css on pages
   that bring their own design (layouts.site 'standalone' => true, e.g. the
   Research section) so the header behaves exactly as on every other page
   without mobile.css restyling the page body. Keep in sync with mobile.css. */
