/* ============================================================
   TBB Pages: carousel (bundle "carousel")
   Used by components/carousel.php. The band is a full-width row on
   the light page; only the cards are dark. The track carries .tbb-dark
   (variables.css), which redefines the colour tokens, so card text,
   tags, chips and buttons switch to their dark style automatically.
   The track is native horizontal scroll with snap; a whole number of
   cards fits the view (no cut-off or faded cards). carousel.js adds
   the buttons, the endless loop and autoplay.
