/* Christine and Ro, public home page.

   The design system is the printed invitation, not an invented one. Three
   card grounds carry the whole page: charcoal with gold foil, warm amber,
   and magenta, the last softened a little from the printed sheet so a full
   band of it is easier to sit in front of than a card is. Headings copy the
   foil treatment, light serif caps with
   wide tracking. The bilingual "English | Deutsch" pipe is the invitation's
   own convention and is reused in the wordmark and footer.

   Deliberately single theme. This is a printed identity reproduced on
   screen, so it does not follow the viewer's light or dark preference. The
   bands supply their own grounds and contrast in both environments. */
