/* ==========================================================================
   Homepage hero slider  (renders the `home_slider` table on home.tpl)
   --------------------------------------------------------------------------
   Markup contract (see templates/includes/home.tpl):

   <div class="buft-slider" data-autoplay="6000" data-interval="6000">
     <div class="buft-slider__viewport">
       <div class="buft-slider__slide is-active"><img src="..." alt=""></div>
       <div class="buft-slider__slide"><img src="..." alt=""></div>
     </div>
     <button class="buft-slider__arrow buft-slider__arrow--prev" ...></button>
     <button class="buft-slider__arrow buft-slider__arrow--next" ...></button>
     <div class="buft-slider__dots"></div>
   </div>

   The viewport height is set by js/home_slider.js from the natural aspect
   ratio of the first image, so slides are never distorted and the hero
   keeps the exact same look as the old single <img>.
