/* ===========================================================================
   Promo carousel.
   ---------------------------------------------------------------------------
   The source artwork is square (1254²) and portrait (1024×1536) — social-media
   shapes, not web banners. Stretching those to a full-width strip would either
   crop the headline off the top or leave a very tall band that pushes the rest
   of the page below the fold.

   So they are shown as posters: each slide is height-capped and centred on a
   tinted backdrop, with the image *contained* rather than cropped. Nothing in
   the artwork is ever cut off, and the section stays a sane height on a laptop.
