/* ==========================================================================
   UP AL — Contact (בואו נדבר)
   The site's closing statement: a centered opening line (echoing the
   Hero's centered composition, bookending the page), then a contact hub
   of four equal premium glass cards — WhatsApp, phone, Instagram, email —
   each a direct action rather than a form field. No personal data is
   collected anywhere in this section.

   The cards reuse the exact glass-card recipe already established for
   Process/Testimonials (four-layer gradient surface, ambient halo,
   hover-triggered sweep, independent slow ambient sweep, chrome accent
   line, icon-glow) rather than inventing new material — this section
   is a variation in content, not in visual language. Every card carries
   an explicit aria-label describing its exact action and destination
   (including whether it opens a new tab), on top of its visible title/
   sub-copy, and the whole surface is the focusable, clickable element.
