/* =============================================================================
   IzeChat — Modern mobile search overlay (isolated, additive)
   -----------------------------------------------------------------------------
   Problem it fixes: on phones the header search opened as a see-through panel
   with no visible input (you couldn't tell what you were typing) and the feed
   bled through behind the results (see bug report). This turns the header search
   into a self-contained, full-screen search — Facebook / Twitter grade — with a
   solid surface, a prominent pill input that clearly shows your query, and clean
   Trending / Recent / Results sections.

   Scope: ONLY `.tag_header .search-container.show` at <=768px. Desktop and the
   AJAX search logic (Wo_GetRecentSearchs / Wo_SearchResult) are untouched — this
   is pure presentation over the existing markup. `.show` is toggled by the search
   handler in container.phtml (#38). Safe areas use the native --ize-safe-* vars
   with an env() fallback, so the overlay clears the status + navigation bars.
   ========================================================================== */

     the overlay reliably fills the screen (needs :has(), fine on modern WebView). */
