/* ============================================================
   DILLY TESTIMONIALS MARQUEE
   1:1 vanilla port of components/ui/testimonials-columns-1.tsx
   + components/demo.tsx (shadcn / motion-react component).

   Tailwind → CSS mapping used here:
     p-10 = 2.5rem · rounded-3xl = 24px · gap-6 = 1.5rem
     max-w-xs = 20rem · mt-5 = 1.25rem · mt-10 = 2.5rem
     shadow-lg shadow-primary/10 → primary-tinted shadow-lg
     tracking-tighter = -0.05em · tracking-tight = -0.025em

   Usage: link this stylesheet + js/dilly-testimonials.js, then
   drop in the <section class="dt-testimonials"> snippet.
   Class names deliberately avoid the "-section" / "-card" /
   "-cta" substrings that site-revolut.css globally overrides.
