/* ============================================
   Horizontal stepper — N numbered nodes on a connector line,
   followed by a single content panel that swaps when a node is
   clicked.

     01   02   03   04   05   06   07
     Step Step Step Step Step Step Step

   Powered by tabs.js (same [data-tabs] markup contract as the
   pill tabs in tabs.css). Active node = coral fill. On hover,
   the circle + label brighten.

   Mobile (≤767px): nodes overflow horizontally with scroll-snap.
   The desktop ::before connector line is hidden — replaced by a
   background-image w/ background-attachment: local so the line
   scrolls WITH the content (the absolute ::before would stop at
   the viewport-right with overflow: auto). Mask-image gradient
   fades the edges; a "1 of N" position indicator appears below.
