/* ============================================================
   Corvair global site chrome: shared header (with dropdown nav)
   and footer for every page in the /cks product area.
   Relies on the design tokens (--bg, --teal-br, --mono, .ms, ...)
   already defined on each page (inline or via docs.css), so it
   layers on top of both the marketing and the docs page styles.
   British spelling, no em or en dashes. JS-free.
