/* Mobile filter panel (search.php + category.php).

   Deliberately does not duplicate any filter markup or logic - the
   ".rld-filter-panel" element wrapped around each page's existing
   includes/search_sidebar.php / includes/category_sidebar.php include
   IS the sidebar. On desktop none of the rules below apply (everything
   here is scoped inside the max-width query) so the sidebar renders
   exactly as it always has. Below 767.98px - the same breakpoint
   styles/mycss.css already uses to hide .mobile-bottom-nav on desktop -
   that same element becomes a bottom sheet toggled by the new
   "Filters" button, and the header/body/footer chrome around it
   (added directly in search.php/category.php, not in the shared
   sidebar partials) becomes visible. Checkbox/select state lives in
   the untouched DOM the whole time, so opening/closing the sheet can
   never lose or reset a selection - only CSS visibility changes. */
