/* ============================================================
   Site search — navbar combobox

   Uses the design tokens already defined in each page's :root.
   This file loads on both stylesheet families, and they disagree
   on one name: home-shell.css calls the border colour --border /
   --border-2 while portfolio-pages.css calls the same values
   --line / --line-2. So the border rules ask for one, then the
   other, then fall back to the literal.

   The results panel is position:absolute so opening it never
   shifts layout — the site holds CLS 0 and must keep doing so.
