/* ---------------------------------------------------------------
   Portfolio card image carousel (arrows, dots, crossfade).

   Structure for a card that should cycle through several photos:

     <div class="portfolio-img portfolio-carousel" data-carousel>
       <div class="portfolio-carousel-track">
         <img class="portfolio-carousel-slide is-active" src="..." alt="..." loading="lazy" />
         <img class="portfolio-carousel-slide" src="..." alt="..." loading="lazy" />
         ... add as many additional <img class="portfolio-carousel-slide"> as needed ...
       </div>
       <button type="button" class="portfolio-carousel-arrow portfolio-carousel-arrow--prev" aria-label="Previous image" data-carousel-prev>
         <svg viewBox="0 0 24 24" aria-hidden="true" focusable="false"><use href="#kr-i-chevron-right-bare"/></svg>
       </button>
       <button type="button" class="portfolio-carousel-arrow portfolio-carousel-arrow--next" aria-label="Next image" data-carousel-next>
         <svg viewBox="0 0 24 24" aria-hidden="true" focusable="false"><use href="#kr-i-chevron-right-bare"/></svg>
       </button>
       <div class="portfolio-carousel-dots-scrim"></div>
       <div class="portfolio-carousel-dots" data-carousel-dots></div>
     </div>

   Cards left with a single <img class="portfolio-carousel-slide">
   automatically get the .is-single class from projects-carousel.js
   and show no arrows/dots — this is the "allowance" for the other
   five cards. To activate the carousel on a card, simply add more
   .portfolio-carousel-slide images inside its .portfolio-carousel-track;
   no other markup or code changes are required.
