/* ========================================
   DESIGN SYSTEM - Ciber Cazadora
   Light blue & gold. Matches securitytranslated.co
   and the Security Translated print/PDF palette.

   Drop-in replacement: every class name from the old
   file is preserved, so no HTML changes are needed.

   Two palettes were merged into one here. The old
   --st-* teal tokens and the --accent amber tokens
   now both point at the same blue & gold values, so
   whichever name your markup uses, it lands right.
