/* ==========================================================================
   CodeToolz Knowledge Center — shared search component
   One results design for Article Search, Resource Search and the entrance
   Unified Search (prototype assets/css/style.css: "Shared inline search
   results (.sr) — identical on all three pages"). Loads after kc-articles.css,
   which provides the tokens, fonts, .btn and .search-field. Also holds the
   resource preview dialog, which search results open on every page.
   Every rule is scoped under `.kc`.
   ========================================================================== */

/* .sr-anchor wraps the .search-field so the results panel floats directly
   below the box. The panel overlays page content — no layout shift.
   Stacking: the site header (Elementor, sticky) sits in a z-index: 10 section,
   so the open panel stays at 9 — above the page, below the sticky header when
   the page scrolls (the prototype's 60 would paint over this site's header). */
