/* ===========================================================
   RJ Minerals — v2
   A working brochure site for tender teams, exporters and
   dealers. Light, editorial, quiet. The stone is the loudest
   thing on the page; nothing else competes with it.

   Type:  Fraunces (display — carved, high-contrast, suits stone)
          Inter    (body/UI — spec tables and forms must be plain)
          Plex Mono(technical labels only)
   Colour: warm paper ground, oxblood for weight, and a cool
          instrument blue carrying every technical label — the
          same survey-equipment accent as the Descend concept,
          so the two read as one brand.
