/* ==========================================================================
Karussell: horizontal scrollbare Kartenreihe mit Prev/Next-Buttons.

Markup:
  <div class="carousel">
    <button class="carousel-nav carousel-prev" type="button">…</button>
    <div class="carousel-track">
      <article class="carousel-card">
        <div class="carousel-card-head">
          <span class="carousel-card-icon" style="--icon: url('../img/foo.svg')"></span>
          <h3>…</h3>
        </div>
        <p>…</p>
      </article>

Achtung: der url()-Pfad in --icon wird relativ zu DIESER Datei (css/) aufgelöst,
nicht relativ zum HTML-Dokument – daher ../img/ und nicht img/.
    </div>
    <button class="carousel-nav carousel-next" type="button">…</button>
  </div>

Verhalten (Scroll je Kartenbreite, Deaktivieren der Pfeile an den Enden):
js/carousel.js. Auf farbigen Sektionen greifen die .accent / .dark / .very-dark
Varianten.
