/* ==========================================================================
   SHOWPIECE 2 — Before / After reveal
   --------------------------------------------------------------------------
   Content: every .compare-item holds a .compare-before image, a .compare-after
   image, two .compare-label elements and its own caption in the HTML.
   With no JS the two photos simply sit side by side.
   assets/js/showpiece-compare.js wraps them in a draggable stage, adds the
   handle and a keyboard-accessible range input. Add another .compare-item and
   it works automatically.
