Testimonial Carousel with Swiper.js (Touch-Friendly, Responsive)

A responsive, touch-friendly testimonial carousel built with Swiper.js, today's go-to carousel/slider library and the natural successor to older jQuery plugins like Slick or Owl Carousel. Includes clickable pagination bullets, prev/next navigation arrows, native touch dragging, and responsive breakpoints (1/2/3 cards depending on screen size) - just two CDN tags, zero jQuery. Copy the HTML, CSS and JS below and drop it into any project.
