/* OGOFX design system, copied from the landing page stylesheet (ogofx.com/assets/css/styles.css):

   Design tokens

/* =====================================================================
   OGOFX design tokens — v3 "Emerald & Champagne"
   Evergreen depth, bone-paper light, champagne for action.
   There is NO blue anywhere in this system: not in links, focus rings,
   charts, gradients, shadows or meta colours.
   Every section stylesheet reads from these. Do not hard-code hex
   values in section CSS; add a token here if one is missing.

   Breakpoints (mobile-first, use min-width media queries):
     --bp-sm   480px   large phones
     --bp-md   768px   tablets portrait
     --bp-lg  1024px   tablets landscape / small laptops (desktop menu)
     --bp-xl  1280px   desktop
     --bp-2xl 1440px   wide desktop (container stops growing at 1240px)
   CSS custom properties can't be used inside @media, so write the px
   values literally:  @media (min-width: 768px) { ... }
