/* ==========================================================================
   Sindesi Search Form — v0.44.22 (E2d, 17/07/2026)
   ==========================================================================
   Shortcode `[sindesi_search_form]` — form ricerca hero-friendly.
   Design isolato con prefisso `.ssf-*` per non collidere con altri moduli.

   ## Layout
     - desktop  ≥ 640px : pill orizzontale (input + button inline)
     - mobile   < 640px : stack verticale (input full-width + button sotto)

   ## Struttura DOM
   .sindesi-search-form          root wrapper
     .ssf-form                    <form>
       .ssf-form__label            <label> con icona SVG + input
         .ssf-form__icon           <svg> lente
         .ssf-form__input          <input type="search">
       .ssf-form__submit           <button>

   ## Focus keyboard
   Il focus va sull'input (autofocus non attivo per non forzare tastiera
   mobile all'apertura homepage). Ring focus outline azzurro Sindesi via
   :focus-within sul .ssf-form (l'intero pill si illumina come Google).

   ## Progressive enhancement
   Zero JS. Submit HTML nativo → browser costruisce URL con query
   `?q={valore}` e naviga a `/dienstleistungen/`.
