/* =========================================================================
   Site Review — landing page layout.

   All colour / typography / spacing comes from the GA UI kit design tokens
   (vendor/ga-ui-kit.css). This file only lays out the page and styles the
   plain elements the kit doesn't ship as components. The look matches
   garutyunov.com because it reads the same --ga-* tokens.
