/* Combo — site styles.
   The palette, geometry and type are lifted from the app itself
   (lib/theme/combo_colors.dart, lib/theme/combo_theme.dart) so the site and
   the product are one visual system rather than two.  The discipline that
   keeps it bright rather than pastel: the page stays near-colourless and a hue
   is either at full strength or not there.  Quiet comes from coverage — a
   thinner ring, a smaller mark — never from mixing a colour into the paper. */
