/* =====================================================================
   Venomers — navigation.css
   Premium Clinical-Light Capsule Navigation
   Scope: Desktop Unified Capsule Bar + Mobile Fluid Drawer
   Follows: venomers-design-system, venomers-architect-manifesto,
            venomers-performance-engineering

   DRY Symmetry: All layout uses CSS Logical Properties
   (padding-inline, margin-inline, inset-inline-*) for native LTR/RTL.
   RTL overrides live exclusively inside :root[dir="rtl"] {} blocks.

   LCP guardrail: No @import, no blocking assets. All animations
   use GPU-composited properties (transform, opacity) only.
