/* =====================================================================
   Venomers — Global CSS (Black / Gold / White)
   Revised & RTL‑safe shared stylesheet for EN + AR

   WHAT CHANGED (high level):
   • Fixed horizontal scroll in RTL by using logical viewport units (vi/vb),
     clipping overflow on the root, and eliminating width leaks in overlays.
   • Tightened Arabic nav typography (letter‑spacing = 0; neutralized opsz) to
     prevent menu growth/overflow.
   • Normalized layout containers and overlay panels with contain/layout rules.
   • Consolidated tokens, cleaned comments, and aligned structure for EN/AR.
   • Kept your black/gold/white aesthetic + glass surfaces intact.
