/* ----- Trigger button (in header) -----
   NOTE: We intentionally do NOT set `display` here.
   Tailwind utility classes (inline-flex, md:hidden) control visibility.
   Pages load Tailwind first, then search.css — so any `display` set here
   would override Tailwind's `md:hidden` and cause both buttons to show.
   The buttons themselves always include `inline-flex` (Tailwind) so they
   render correctly below md and at md+.
