   Tradevine Theme — Design System
   =========================================================================
   Brand identity for a produce brokerage platform.

   Color philosophy:
     • Green (produce vitality) — primary accent, CTAs, success states
     • Navy (trust, banking-grade) — backgrounds, depth, conservative
     • Amber (orange/citrus warmth) — secondary highlights, urgency
     • Earth grays — body text, dividers, cards
