/* ==========================================================================
   DermPRO Before/After Gallery
   Self-contained styles: twentytwenty slider core + gallery page layout.
   Class names match the legacy CMS implementation so per-theme LESS
   (e.g. surgeryvp web/css/source/before-after.less) keeps applying on top.
   Accent colors are exposed as custom properties on .before-after-gallery
   so themes can re-brand without overriding individual rules.
