/* ==========================================================================
   Wantij — site styles

   Colour and type come from the app, not from a second design decision:
   the tokens below are the day theme in
   Wantij/DesignSystem/Foundation/WantijTheme.swift, as restated by the
   Wantij design system (tokens/colors.css, [data-theme="day"]). Change one
   there and change it here, or the site and the app drift.

   The site uses the day theme: the "Almanak" design, light and editorial,
   with the tide table as its hero. Night stays the app's default; day is a
   full peer there, and it is the one a printed almanac reads in.
