/**
 * TIF Carousel — primitives CSS réutilisables
 * ------------------------------------------------
 * Classes génériques pour tout carrousel horizontal (drag / flèches / fondu).
 * Les avis ([tif_reviews]) les consomment via des classes doubles :
 *   .tif-carousel.tif-reviews-carousel
 *   .tif-carousel__viewport.tif-reviews-viewport
 *   etc.
 *
 * Réutilisation ailleurs :
 *   1. Enqueuer ce fichier (handle WP : tif-carousel)
 *   2. Markup :
 *      <div class="tif-carousel tif-carousel--fade-x">
 *        <button class="tif-carousel__arrow tif-carousel__arrow--prev">…</button>
 *        <div class="tif-carousel__viewport">
 *          <div class="tif-carousel__track">
 *            <div class="tif-carousel__slide">…</div>
 *          </div>
 *        </div>
 *        <button class="tif-carousel__arrow tif-carousel__arrow--next">…</button>
 *      </div>
 *   3. JS : tif-reviews.js peut servir de base (initCarousel) — à factoriser
 *      plus tard en tif-carousel.js si besoin.
 *
 * Variables (surchargeables sur un parent) :
 *   --tif-carousel-gap
 *   --tif-carousel-arrow-w / -h
 *   --tif-carousel-pad-x   (place flèches + ombres)
 *   --tif-carousel-fade-x  (largeur du fondu latéral)
