/* ===========================================
   GILLMONT OVERSEAS – Optimized Global CSS
   Performance principles applied:
   · font-display:swap → no invisible text flash
   · will-change only on actively animated props
   · transform/opacity only (compositor-only props)
   · contain:layout style on isolated components
   · prefers-reduced-motion respected
   · transition targets specific properties (not 'all')
   · box-shadow on pseudo-elements (avoids repaint)
   · mobile-nav hidden via visibility+opacity (GPU layer, no layout shift)
