   Homepage reel, references page (justified mosaic / mobile masonry) and the
   full-screen viewer with numbered hotspots. Built from the References design
   (references.css + the design-system components it relies on); tokens are
   bridged to main.css so the site's colours, font and light/dark mode apply.
