/* =========================================================
 FEATURED SECTION + SIDE-SCROLLING ROW
 ---------------------------------------------------------
 .featured-track is one horizontal row of cards:

   display: flex + overflow-x: auto  -> a sideways row that
                                        scrolls left/right
   scroll-snap-type: x mandatory     -> scrolling stops neatly
                                        on a card, not halfway
   flex: 0 0 <width>                 -> every card keeps the
                                        same width instead of
                                        squishing to fit

 On desktop, the arrow buttons in the header scroll the row
 by one card. With a trackpad/touch you can also just swipe.
 The arrows hide themselves when all cards already fit.
