Results Reel: before/after review carousel

New page-builder section for transformation-led stores: supplements, skincare, haircare, dental, fitness. Each slide pairs a customer's before and after photos with their star rating, an optional verified badge, result tags and a "uses [product]" link, plus an optional shop button. Shoppers browse by a roster of result thumbnails (the after photos become the navigation) or plain dots, with arrows and optional autoplay. One section-level proof bar anchors the set with a big stat, a claim and fine print. Autoplay is off by default, everything is keyboard-accessible, and it recolors to your brand. Add it from the section picker under Comparison.
