/* ---------- mobile header fix: search bar was overflowing the nav row ----------
   Two separate .nav-search rules earlier in this file conflict (one meant for
   desktop's right-side button style, one from an older layout); on small
   screens the later one won and forced the search box to a fixed ~300px
   width, which doesn't fit next to the logo + menu button and pushed it off
   the right edge of the screen.
   First attempt was to let it wrap onto its own row, but the logo text is
   wide enough on mobile that this pushed the menu button down too. Settled
   on: hide the full header search box on mobile (Catalog page has its own
   full search + filters, so nothing is lost) and show a compact search icon
   instead, linking straight to the catalog. To make room, the "HEX HARDWARE"
   wordmark is hidden on mobile too (the logo mark already reads "HEX
   HARDWARE" on its own) and the logo is shown a bit larger in its place. */
