A testimonial carousel that gives one client quote the whole stage in display type. A radio-driven avatar row, a figcaption crossfade and native label/radio pairing mean the quotes already switch with no JavaScript. JS adds an SVG ring around the active avatar that fills over the slide duration (no @keyframes), auto-advance, arrow-key and swipe navigation, Previous/Next buttons, and a Pause button; autoplay pauses on hover or focus. Section options: data-duration (ms, default 6000) time per slide; data-autoplay (true|false) advance on its own.
