Three product surfaces, one design system. Koide is really three products that have to feel like one: the marketing site (selling), the couple's dashboard (configuring the details with tabs for General, Sections, Timeline, Places, Quiz, Messages, Photos, Analytics), and the public wedding microsite each couple ends up with (the artefact: hero, countdown, navigation, gallery). Same high-contrast display serif, same cream-and-gold palette, same italic accents on emphasised words, applied to three different problems.
