/* ── Tripnex search-form widget ──────────────────────────────────────────
   Используется на /, /tour. Рендерит шапку поиска с пятью полями-кнопками:
   город вылета / страна / даты / ночей / туристы — каждое раскрывается
   в попап (см. скриншоты из ТЗ).

   Подключение:

     <div id="sf"></div>
     <script src="/static/search-form.js"></script>
     <script>mountSearchForm('#sf', { onSubmit: (params) => location.href='/tour?'+new URLSearchParams(params) });</script>
