   geo-chrome.css — redesigned shared header (nav) + footer.
   Loaded globally from base.html, so it must NOT restyle bare elements
   (body, h1..h6, a, p) — that would break the ~45 un-ported pages that still
   run the vendored Bootstrap 4 "bingo" theme. Everything here is scoped under
   .geo-nav* / .geo-footer* and uses --geo-* custom properties so nothing
   collides with the existing theme.
