/* ============================================================
   Bert – Privilege Escalation Template Styles
   Pixel-perfect port of privilege-escalation.html
   All rules scoped under .bert-page-privilege-escalation

   FIXES APPLIED:
   1. All Orbitron/display headings use clamp() for full mobile responsiveness
   2. Nav buttons use ◀/▶ + font-variant-emoji:text
   3. All 8 defense cards present (2-col icon-wrap layout)
