/* =============================================================
   Viglet Design System — product-site layer (VDS214)
   ---------------------------------------------------------------
   The rules behind `./site`, as plain CSS so a page needs no Tailwind
   build to take them. Every colour is a preset token, so the ground
   follows `data-tone` and the mode follows `data-theme`: set
   `data-tone="warm"` on <html> for the clay family, `navy` for a blue one.

   Import after the preset (or `./styles`):
     @import "@viglet/viglet-design-system/preset";
     @import "@viglet/viglet-design-system/site.css";

   `.vg-site` on <body> gives the page its face, ground and glow; the
   components work without it.
