/* ============================================================
   BG PLOMBERIE CHAUFFAGE — Comparateur Avant / Après (v16)
   Composant unique, remplace les deux anciens sliders
   (premium-fx v13 + style.css v15) qui se marchaient dessus.

   Structure :
   .cmp-set                → bloc vitrine (viewer + panneau infos + onglets)
     .cmp-viewer           → empile les projets (un seul visible)
       figure.cmp          → un projet avant/après
         .cmp-stage        → zone interactive (photos + poignée)
         figcaption        → titre / lieu / description du projet
     .cmp-side             → panneau éditorial (texte du projet actif + onglets)

   Ajouter un projet = copier un <figure class="cmp"> (voir README).
