   EPYSO — HERO SLIDER  (hero-slider.css)
   
   Cinematic full-bleed slideshow. Replaces .rr-hero entirely.
   Uses existing --rr- tokens so light/dark theme works automatically.

   Paste this into style.css AFTER the existing :root / .rr-hero block
   (around line 3780), OR @import it, OR inject via wp_head.
