/* CharityChannel Press shared chrome for the aardvark Worker's pages: the masthead,
   the primary nav and the footer, lifted from ccsite's site.css (the design-system
   source; mirror any change there into this file). Loaded by the four app pages
   and the /framework page in place of the July transplant of the WordPress
   masthead, which went with WordPress on 2026-09-13. The links in the markup are
   absolute (this Worker's pages serve on two hosts), so the current-page marks
   match on the end of the href. The header sits at z-index 40 here: the app's
   Getting-around panel and email gate dim the page at 50 and 60 and must cover
   it. Fonts and tokens: the app's site.css and the framework page's own style
   block define the same faces; the tokens are repeated here so the file stands
   alone on the framework page. */
