/* ============================================================
   VANTORA DESIGN SYSTEM
   Loaded AFTER each page's own stylesheet, so it only has to
   redefine the tokens and restyle the parts that carry the brand.

   Brand idea: the logo is a star in orbit. The product is black
   and white; the one bold move is the black brand rail with the
   white mark. Everything else stays quiet. Colour appears only
   where it carries meaning (status, focus, links).
