/* ============================================================
   TRADERS HUB — refresh/v1
   Layered on top of styles.css. Removing the <link> to this
   file reverts every change in this refresh.
   ------------------------------------------------------------
   Goals (surgical, not a rewrite):
   1. One quiet, modern accent system (single emerald tone).
   2. Tighter, more confident type scale.
   3. More generous vertical rhythm between sections.
   4. Product-card grid that feels intentional (equal headers).
   5. A single primary hero moment with subtle chart motion.
   6. Softer, glassier surfaces on cards; less border noise.
