/* ==========================================================================
   FairTech Product Detail Page — premium two-column layout.
   Page-scoped (only product-details.php loads this via $extra_head).
   All classes below are new wrapper/utility classes added around the
   existing markup — no Splide id (#main-carousel etc.), form field, or
   button id/name was renamed, so gallery sync, the fullscreen modal, and
   the add-to-cart POST all keep working unchanged.
