   home2 — Enhanced Chain Navigation in Sidebar
   ═════════════════════════════════════════════════════════════
   Replaces the basic chain links with a rich, prominent UI:
   • Each chain card has its brand color glow
   • Live hover effect with translation + glow expansion
   • Active state (current page) with prominent indicator
   • Real chain logo SVGs
   • "Live" indicator dot for chains with high activity
