/* ============================================================
   WEIYA V4 — B2B foreign-trade template build (Home-22 structure)
   Palette extracted from source: #0b6cf2 / #102a43 / #f7f9fc

   V4 CHANGES vs V3 (InfinityFree compatibility):
   1. Google Fonts @import REMOVED. InfinityFree free tier throttles
      outbound requests and has no SLA, so a render-blocking external
      CSS fetch is a real risk. Replaced with a system font stack that
      resolves instantly with zero network cost. On Windows the stack
      maps to Open Sans / Roboto-adjacent faces via fontconfig.
   2. Added font-family variables so the stack is defined in one place.
   3. Added .no-wrap / focus-visible / reduced-motion guards for a11y.
