/* ==========================================================================
   De Caires Data — single stylesheet
   ==========================================================================
   The De Caires house style, inverted: where De Caires Classics is cream and
   gold on black, this side of the brand is black and gold on white. Same
   typography (Cormorant Garamond + DM Sans), same gold hairlines, same
   generous vertical rhythm — so the two sites read as one company.

   Everything visual derives from :root, so brand tweaks are a one-block
   change.
