/* ===========================================================================
   Vista Destination — results search widget & checkout form (2026 refresh)
   ---------------------------------------------------------------------------
   WHY THIS FILE EXISTS
   vista-flight.css carries three overlapping generations of rules for the
   results search widget, several of them !important. Editing them in place is
   a specificity fight nobody wins. Everything here uses fresh namespaces
   (.vd-rs-* for the results search, .vd-co-* for the checkout form) that the
   legacy rules cannot reach, so behaviour is predictable.

   Loaded last in layouts/header.php. Two small, deliberately scoped overrides
   for legacy classes are marked below.
