   NAN HERO SLIDER — Performance-optimised
   FCP/LCP/SI < 1s strategy:
     • Critical above-fold CSS inlined via nan_slider_critical() wp_head hook
     • This file loads non-critical slider enhancements (deferred)
     • Slide 1: fetchpriority=high + loading=eager
     • Slides 2-N: loading=lazy — never block first paint
