/* ============================================================
   Refari — Web / Marketing Page Starter
   The reusable design tokens + core components for a Refari
   MARKETING / LANDING page (not policy/document pages — those
   use a calmer template; see /refari/policy/).

   Reference implementation: https://aivisibility.refari.co/
   Pairs with the brand fundamentals at branding.refarigroup.com/refari/

   THE ONE RULE THAT MATTERS MOST:
   Teal (#4CF8EE) is a DARK-BACKGROUND accent only. On light
   backgrounds use Blue (#0074BC). Teal on light fails contrast
   and looks washed out — never do it.
