/* ============================================================
   SH Energy v8r1 — CHROME & THEME OVERRIDE (Phase 2)
   Loaded LAST, after legacy content CSS.
   Purpose: unify nav / footer / mobile-menu to the v8r1 design
   language across all pages WITHOUT breaking legacy content
   layouts. Legacy content classes (hero__grid, cap__grid, etc.)
   keep their original stylesheet; only shared chrome + accents
   are re-skinned here.
   - No opacity:0 default (core content visible without JS)
   - Working mobile menu (open/close/Escape/overlay), no h-overflow
   - RTL-aware for /ar/ pages
   - prefers-reduced-motion respected
