/* =============================================================
   Testimonials — Modern CSS scroll-snap with scroll-state
   Depends on variables.css being loaded first.

   How it works:
   1. .testimonials-slider: scroll container with snap
   2. .testimonial-slide: each slide is a scroll-state container
   3. .testimonial-card: content that reacts to snapped state
   4. @container scroll-state(snapped: inline): active styling
