   A native <select>'s closed state can be styled (above), but its open
   option list is always rendered by the OS — Chrome, Firefox and
   especially Safari/macOS/iOS each draw it differently and none of it is
   reachable by CSS. script.js progressively enhances every .filter-select
   into the widget below (own HTML/CSS end to end, so it's pixel-identical
   everywhere) and forwards picks back onto the real <select> — so the
   existing onchange="..." behavior in page-blog.php/search.php keeps
   working untouched. If JS doesn't run, the native select above is left
   alone as a fully working fallback. */
